Which of the reagents listed below could be added to water to make `0.1M` solutions of each of the following ions?
a. `overset(o+)NH_(4)`
b. `CH_(3)COO^(Theta)`
c. `C1^(Theta)`
i. `NH_(3)` ii. `NH_(4)C1`
iii. `CH_(3)COOH`
iv. `CH_(3)COONa`
v. `HC1`
vi. `NaC1`.

Text Solution

Verified by Experts

a. ii. `NH_(4)C1` will give `0.1M overset(o+)NH_(4)` ion to a solution. `(NH_(3))`, a weak electorlyte does not dissociate sufficiently to give `0.1M overset(o+)NH_(4)` ions).
b. iv. `CH_(3)COONa CH_(3)COOH` is a weal electrolyte, does not dissociate sufficiently)
c. (v. and vi.) `HC1` and `NaC1` both are strong electrolytes which are completely ionic.
