zad.1:
Trzema sposobami otrzymaj :
a) propionian wapnia
b) maślan magnezu
propionian wapnia - (C2H5COO)2Ca
2C2H5COOH + Ca ---> (C2H5COO)2Ca + H22C2H5COOH + CaO ---> (C2H5COO)2Ca + H2O2C2H5COOH + Ca(OH)2 ---> (C2H5COO)2Ca + 2H2O
maślan magnezu - (C3H7COO)2Mg
2C3H7COOH + Mg ---> (C3H7COO)2Mg + H22C3H7COOH + MgO ---> (C3H7COO)2Mg + H2O2C3H7COOH + Mg(OH)2 ---> (C3H7COO)2Mg + 2H2O
NAJ?
a)
2C₂H₅COOH + Ca ---> (C₂H₅COO)₂Ca + H₂^
2C₂H₅COOH + CaO ---> (C₂H₅COO)₂Ca + H₂O
2C₂H₅COOH + Ca(OH)₂ ---> (C₂H₅COO)₂Ca + 2H₂O
b)
2C₃H₇COOH + Mg ---> (C₃H₇COO)₂Mg + H₂^
2C₃H₇COOH + MgO ---> (C₃H₇COO)₂Mg + H₂O
2C₃H₇COOH + Mg(OH)₂ ---> (C₃H₇COO)₂Mg + 2H₂O
