SS1 Chem basicity of acids

1. HA and zinc metal
2HA + Zn → ZnA2 + H2

2. H2B and calcium carbonate
H2B + CaCO3 → CaB + H2O + CO2

3. HA and copper(II) oxide
2HA + CuO → CuA2 + H2O

4. H2B and sodium hydrogencarbonate
H2B + 2NaHCO3 → Na2B + 2H2O + 2CO2

1. Zn andi HA
Full equation: Zn(s) + 2HA(aq) --> ZnA2(aq) + H2(g)
Ionic equation: Zn(s) + 2H+(aq) --> Zn2+(aq) + H2(g)

2.CaCO3 and H2B
Full equation: CaCO3(s) + H2B(aq) --> CaB+ H2O(l) + CO2(g)
Ionic equation: CaCO3(s) + 2H+(aq) --> Ca2+(aq) + H2O(l) + CO2(g) OR there is no ionic equation
If CaB is CaSO4, no ionic equation can be wriiten as CaSO4 is insoluble in water

3. CuO and HA
Full equation: CuO(s) + 2HA(aq) --> CuA2(aq) + H2O(l)
Ionic equation: CuO(s) + 2H+(aq) --> Cu2+ (aq) + H2O(l)

4. H2B and NaHCO3
Full equation:
1. 2NaHCO3(s) + H2B(aq) --> Na2B(aq) + 2H2O(l) + 2CO2(g)
2. 2NaHCO3(aq) + H2B(aq) --> Na2B(aq) + 2H2O(l) + 2CO2(g)
Ionic equation:
1. NaHCO3(s) + H+(aq) --> Na+(aq) + H2O(l) + CO2(g)
2. HCO3-(aq) + H+(aq) --> H2O(l) + CO2(g)
