A salt properties: acid salt of a strong acid
2 pH: acidic aqueous solution. Strong electrolyte, fully ionized, generating strong acid solution: NaHSO4 = Na + + H + + SO42-
Note: not fully ionized hydrogen sulfate, is in strong acid. (High school textbooks as the fully ionized hydrogen sulfate)
It can be reacted with a base. NaHSO4 + NaOH == Na2SO4 + H2O
3 metathesis reactions can occur with weak acid: NaHSO4 + NaHSO3 == Na2SO4 + SO2 ↑ + H2O
NaHSO4 + NaHCO3 == Na2SO4 + CO2 ↑ + H2O
Ionic equation: H + + SO42-+ HSO3-== SO2 ↑ + H2O + SO42-
H + + SO42-+ HCO3-== CO2 ↑ + H2O + SO42-
4, and BaCl2, Ba (OH) 2 reaction: NaHSO4 + BaCl2 == NaCl + HCl + BaSO4 ↓
NaHSO4 + Ba (OH) 2 == NaOH + H2O + BaSO4 ↓
Involving ionic equation: SO42-+ Ba2 + == BaSO4 ↓
H + + SO42-+ Ba2 + + OH-== BaSO4 ↓ + H2O
If the Ba (OH) 2 small, then the equation is expressed as: 2H + + SO4 2 – + Ba2 + +2 OH-== BaSO4 ↓ +2 H2O
