Acid and Base Word Equations Chemistry Tutorial

For the chemical reaction between an acid and a metal hydroxide (base), the products are a salt and water. metal hydroxide + acid → salt + water . If we are given the following word equation: calcium hydroxide + hydrochloric acid → calcium chloride + water . then we can identify the reactants and products of the chemical reaction:


Nitric acid, calcium salt, tetrahydrate; Calcium(II) nitrate, tetrahydrate (1:2:4 The action of nitric acid on a metal usually results in reduction of the acid Organic nitrates are esters formed by reaction of nitric acid with the hydroxyl (-OH) group in an alcohol.

Demonstrations - Calcium + Water

Calcium + Water . Calcium is a silvery-white metal; it is relatively soft, but much harder than sodium metal.Calcium is a meer of the alkaline-earth metals (Group II on the periodic table); these metals react vigorously with water, although not as violently as the Group I metals such as sodium or potassium:. Ca(s) + 2H 2 O(l) ——> Ca(OH) 2 (aq) + H 2 (g)
