Question

Equal volumes of three acid solutions of PH 2,5
and 6 are mixed in a beaker. Which of the
following is correct for resulting solution?
(1) [H+] = 5.6 x 10-5 (2) [H+] = 1.2 x 10-2
(3) [H+] = 3.3 * 10-4 (4) [H+] = 3.3 x 10-3​

Answer 1

Option 4 is correct for resulting solution.

Explanation:

First consider the molarity of the given mixture

$M=\frac{M_{1}V_{1}+M_{2} V_{2}+M_{3}V_{3}     }{3}$

consider the first solution:

(pH=2)[$H_{3} O^{+}$]=[$10^{-2} M$

consider the second solution:

(pH=5)[$H_{3} O^{+}$]=$10^{-5} M$

consider the third solution:

(pH=6)[$H_{3} O^{+}$]=$10^{-6} M$

Total $[H_{3} O^{+} ]$=$\frac{10^{-2}+10^{-5} +10^{-6}  }{3}$

$[H_{3} O^{+} ]=0.003337$

$[H_{3} O^{+} ]=3.3*10^{-3}$
