Is chromate aqueous
WebSodium chromate is a yellow crystalline solid dissolved in a liquid medium, probably water. It is soluble in water. It is toxic by inhalation, ingestion and/or skin contact. It is noncombustible. It is used to make pigments for paints and inks, other chemicals, and as a wood preservative. Hazards What is this information? Reactivity Alerts WebFinal answer. Step 1/3. The solubility of silver chromate in a solution containing potassium chromate can be determined by considering the common ion effect. Since potassium chromate is a soluble salt, it dissociates completely in aqueous solution to give potassium cations (K^+) and chromate anions (CrO4^2-): K A 2 CrO A 4 ( s) 2 K A + ( aq ...
