Phosphoric acid and zinc
WebPhosphoric acid is a corrosive acid that can form three different classes of salts, namely primary phosphates, dibasic phosphates and tribasic phosphates. Phosphoric acid is soluble in water. It is incompatible with strong caustics and it is corrosive to ferrous metals and alloys. It readily reacts with metals to form flammable hydrogen gas. WebThe reaction between zinc oxide and phosphoric acid is exothermic and requires a strict mixing protocol to control excess heat generation. A small increment of powder is first …
