Select every statement that is true about the relative acidity of salt solutions.
NH4F is more acidic than NH4Cl. |
||
ZnBr2 is more acidic than CaBr2. |
||
NaHSO4 is more acidic than NaNO3. |
||
NaClO is more acidic than NaClO2. |
1) NH4F is more acidic than NH4Cl. it is false . because NH4F is neutral but NH4Cl is purely acidic satl because it is formed from strong acid HCl and weak base NH3
2) ZnBr2 is more acidic than CaBr2. TRUE
here ZnBr2 is the salt of weak base and strong acid . so acidic character is dominent. but CaBr2 is the salt of strong acid and stron abse so it is neutral
3) NaHSO4 is more acidic than NaNO3 (TRUE)
reason . still NAHSO4 one acidic proton so it is more acidic
4) NaClO is more acidic than NaClO2 (False)
HClO is weak acid than HClO2. so NaClO is stronger base than NaClO2. if NaClO is stroner base its acidity is lesser than NaClO2
