Which of the following salts gives an acidic solution in water?

Options

A. `CH_(3)COONa`
B. `NH_(4)Cl`
C. NaCl
D. `CH_(3)COONH_(4)`

Answer

B

Explanation

Among the given salts, only `NH_(4)Cl` gives acidic solution in water.
`CH_(3)COONa + H_(2)O hArr CH_(3)COOHunderset("weak acid") + NaOHunderset("Strong base")`
`NH_(4)CI + H_(2)O hArr NH_(4)OHunderset("Weak base") + HCIunderset("Strong acid")`
`NaCl + H_(2)O hArr NaOHunderset("Weak base") + HCIunderset("Strong acid")`
`CH_(3)COONH_(4) + H_(2)O hArr CH_(3)COOHunderset("weak acid") + NH_(4)OHunderset("Weak base")`
