Question step step one9. The species H_dosO, HCO₃ – , HSO_cuatro – and NH₃ can act both as Bronsted acid and base. For each case, give the corresponding conjugate acid and base. Answer:

Question 20. (a) OH – ions (b) F – (c) H + (d) BCI₃ Answer: (a) OH – ions can donate an electron pair and act as Lewis base. (b) F – ions can donate an electron pair and act as Lewis base. (a) H + ions can accept an electron pair and act as Lewis base. (b) BCl₃ can accept an electron pair since Boron atom is electron deficient. It is a Lewis acid.

Question 21. Predict the acidic, basic or neutral nature of the solutions of the following salts: NaCI, KBr, NaCN, NH₄NO₃, NaNO₂, KF. Answer: NaCN, NaNO₂, KF solutions are basic, as they are salts of strong base, weak acid. NaCl, KBr solutions are neutral, as they are salts, of strong acid, strong base. NH₄NO₃ solution is acidic, as it is a salt of strong acid, weak base.
