Using the reagents issued, carry out an almost sequential transformation of substances: a) calcium oxide-calcium hydroxide-salt b) phosphorus oxide 5-phosphoric acid-salt write the reaction equations give the name of the salts
a)
1. CaO + H2O = Ca (OH) 2 (obtaining calcium hydroxide)
2.Ca (OH) 2 + CO2 = CaCO3 + H2O (salt production)
b)
1.P2O5 + 3H2O = 2H3PO4 (obtaining phosphoric acid)
2.H3PO4 + 3NaOH = Na3PO4 3H2O (salt preparation)
a) salt name: calcium carbonate
b) the name of the salt: sodium phosphate
