Applied to the skin and mucous membranes, silver nitrate is used either in stick form as lunar caustic (or caustic pencil) or in solutions of 0.01 percent to 10 percent silver nitrate in water. The stick is used for removing warts and granulation tissue and for cauterizing wounds and ulcerations.
Also, is silver chloride harmful?
Unusual Fire & Explosion: May emit toxic fumes of hydrogen chloride and silver oxide if involved in a fire. Effects of Exposure: Chlorides vary widely. Sodium chloride (table salt) has very low toxicity, while carbonyl chloride (phosgene) is lethal in small doses (Sax, Dangerous Properties of Industrial Materials).
What makes silver chloride?
Silver nitrate and sodium chloride are both soluble. When you mix their solutions together, you make soluble sodium nitrate and insoluble silver chloride: silver nitrate + sodium chloride → sodium nitrate + silver chloride. AgNO3(aq) + NaCl(aq) → NaNO3(aq) +AgCl(s)
What is the chemical name for AgCl?
Is it bad to get silver nitrate on your skin?
Silver nitrate is toxic and corrosive. Little exposure to the chemical will not produce immedi- ate or even any side effects other than the purple skin stains, but with more exposure, side effects will become more noticeable. It is very poisonous and can cause burns.
Can silver nitrate burn skin?
Silver nitrate stains skin and can even cause burns. The material does not at first stain, it is just absorbed into the skin. Later, exposure to light causes it to darken and then turn jet black.
What does silver nitrate do for a wound?
Silver Nitrate Stick Therapy is an antimicrobial, and has anti-inflammatory and healing characteristics. Silver Nitrate Stick Therapy is a chemical cautery agent which is used to: a. Remove excess granulation tissue around stomas such as gastrotomy and tracheotomy stomas.
What happens when you eat silver nitrate?
Some of the silver that is eaten, inhaled, or passes through the skin may build up in many places in the body. Exposure to dust with high levels of silver compounds such as silver nitrate or silver oxide may cause breathing problems, lung and throat irritation, and stomach pain.
What are the hazards of working with silver nitrate?

What does silver nitrate do?
Fused silver nitrate, shaped into sticks, was traditionally called “lunar caustic”. It is used as a cauterizing agent, for example to remove granulation tissue around a stoma. Silver nitrate is also used to cauterize superficial blood vessels in the nose to help prevent nose bleeds.
What is the use of silver nitrate gel?
Scientists in India are reporting successful laboratory tests of a new and potentially safer alternative to silver-based gels applied to the skin of burn patients to treat infections. With names like silver sulfadiazine and silver nitrate, these germ-fighters save lives and speed healing.
How do you get silver nitrate?
Part 2 Making Silver Nitrate
Gather the necessary materials.
Fill a clean glass container with concentrated nitric acid.
Wrap the aluminum wire around the silver.
Place the piece of aluminum-wrapped silver in the nitric acid.
Heat the acid until the silver starts to bubble.
Wait until the silver completely dissolves.
What do you use silver nitrate sticks for?
A caustic pencil (or silver nitrate stick) is a device for applying topical medication containing silver nitrate and potassium nitrate, used to chemically cauterize skin, providing hemostasis or permanently destroying unwanted tissue such as a wart, skin tag, aphthous ulcers, or over-production of granulation tissue.
What is silver nitrate ointment used for?
Silver Nitrate is a prescription topical solution used in treating wounds and burns on the skin as an anti-infective agent. Adult and Pediatric: Sticks: Apply to mucous membranes and other moist skin surfaces only on area to be treated.
Can silver nitrate dissolved in water?
There is no reaction between the two. Silver nitrate simply dissolves in pure water. If, however, you have any chloride or other halide in water, silver nitrate reacts with that to form an insoluble precipitate of silver chloride or the respective halide. AgNO3 is Colorless (white) solid salt soluble in water.
What is silver chloride used for?
Uses. The silver chloride electrode is a common reference electrode in electrochemistry. Silver chloride’s low solubility makes it a useful addition to pottery glazes for the production of “Inglaze lustre”. Silver chloride has been used as an antidote for mercury poisoning, assisting in the elimination of mercury.
How does silver nitrate work to stop bleeding?
The silver nitrate and potassium nitrates in caustic stick is in a dried, solid form at the tip of a wooden or plastic stick. When the material is applied to a wound or lesion, the tissue moisture or blood dissolves the dried nitrate salts, which then chemically burn the tissue. It requires moisture for activation.
What is silver nitrate cream used for?
Medical Uses for Avoca Silver Nitrate. With well-established antiseptic and antimicrobial properties, silver nitrate from an applicator or pencil is applied topically usually in aqueous solution and used as a haemostatic, for pain relief in certain conditions and for the removal of small quantities of unwanted tissue.
How do you cauterize a wound?
Heat the metal until it is hot, but not so hot that it glows red or white. Place the metal on the wound. Because it is easy to hold the metal to the wound for too long (and thereby kill healthy tissue), you’ll want to cauterize in short, one- to two-second bursts.
Is silver nitrate flammable?
Silver Nitrate is not combustible, but it is a STRONG OXIDIZER that enhances the combustion of other substances. Silver Nitrate itself does not burn. POISONOUS GASES ARE PRODUCED IN FIRE, including Silver Oxides and Nitrogen Oxides.
Is silver nitrate good for burns?
Topical antimicrobials for the prevention and treatment of burn wound infection include mafenide acetate, silver sulfadiazine, silver nitrate solution, and silver-impregnated dressings. Antibiotic prophylaxis at the time of wound manipulation has also been studied in patients with burns.
What does Hypergranulation mean?
Hypergranulation, which is also known as overgranulation, exuberant granulation tissue or proud flesh, usually presents by secondary intention in the wound healing process. Granulation tissue is comprised of new connective tissue and tiny blood vessels that form on the surfaces of a wound during the healing process.
How do you make silver nitrate solution?
Silver Nitrate Solution Preparation
Take about 100 ml of water in a cleaned and dried 1000 ml volumetric flask.
Add about 17 gm of Silver Nitrate with continues stirring.
