Silver Acetate is a white crystalline chemical compound with the molecular formula C2H3AgO2. It has a slightly acidic odor. Silver Acetate is a photosensitive compound i.e., sensitive to light. It is a moderately water-soluble crystalline silver source that decomposes to silver oxide on heating. Silver Acetate is used in the medical field to manufacturing anti-smoking medicine and also in the preparation of reflective, conductive silvered polymer films. The other names for Silver Acetate are Silver monoacetate and Silver ethanoate.

Question 1: Is silver acetate an acidic compound or an alkaline compound?
Silver acetate is an acidic compound. It is a strong acid and come under the class of acetate salts. Acetate is a type of salt formed by the combination of acetic acid with some base.
Question 2: Find the molecular weight of Silver Acetate?
Molecular formula of silver acetate is C2H3AgO2.
Atomic weight of each Carbon atom = 12.011
Atomic weight of each Hydrogen atom = 1.00784
Atomic Weight of Silver = 107.8682
Atomic weight of each Oxygen atom = 15.999
Molar mass of C2H3AgO2 = (2 × 12.011) + (3 × 1.00784) + 107.8682 + (2 × 15.999)
Question 3: Is Silver Acetate an Organic/Inorganic compound?
Any compound consists of carbon atom is considered as an Organic compound. In silver acetate Carbon atoms are present. So it is considered as Organic compound.
Question 4: Is Silver acetate soluble in water?
Silver acetate is partially soluble in water. But its solubility increases with increase in temperature. Silver acetate is soluble in Dilute HNO3.
