Decomposition of KHCO3

2KHCO3=K2CO3+CO2+H2O

Ionic equation of carbonate ion

2OH- + 2CO2 = 2HCO3-

Decomposition of HClO

2HClO=2HCl+O2

Buffer equation carbonic acid and hydrogen carbonate

H+ + HCO3- = H2CO3

OH- + H2CO3 = HCO3- + H2O

Or

H+ + HCO3- = H2O + CO2

OH- + HCO3- = CO3(2-) + H2O

Buffer equations dihydrogen phosphate (acid)

H2PO4- + OH- = HPO42- + H2O

HPO4(2-) + H+ = H2PO4-

Or,

H2PO4- + H+ = H3PO4

HPO4(2-) + OH- = PO4(3-) + H2O
