Question

Consider 0.25 M solutions of the following salts. For each salt, indicate whether the solution is acidic, basic, or neutral.

Consider 0.25 M solutions of the following salts. For each salt, indicate whether the solution is acidic, basic, or neutral. KC2H302 NaCl CH3NH3I basic acidic basic eaSr(CIO4)2 basic acidcSr(OC6H5)2 C5H5NHBr Reference the Ka and Kb Tables, and think about the acid/base properties of each species present. For conjugate acid/base pairs, Kw Ka x Kb. For salt solutions, remember: A. +1 and +2 metal ions generally have no acidic/basic properties. B. the conjugate bases of weak acids are weak bases (1 > Kb > 10-14). C. the conjugate bases of strong acids are worse bases than water (Kb 10-14). D. the conjugate acids of weak bases are weak acids (1 > Ka > 10-14). Submit Answer Incorrect. Tries 1/45 PreviousTries

Explanation / Answer

Solution :-

When the salt if formed by strong acid and strong base then its neutral

Weak acid and strong base then its basic

Strong acid and weak base then its acidic

KC2H3O2 is basic because salt of weak acid and strong base

NaCl is neutral because salt of strong acid and strong base

CH3NH3I is acidic because salt of strong acid and weak base

Sr(ClO4)2 is neutral because salt of strong acid and strong base

C5H5NHBr is acidic because salt of strong acid and weak base

Sr(OC6H5)2 is basic because its salt of strong base and weak acid
