Equilibrium Question 903
Question: 100 mL of 1 M $ HCl $ is mixed with 50 mL of 2 M $ HCl $ . Hence, $ [ H_3{O^{+}} ] $ is:
Options:
A) 1.00 M
B) 1.50 M
C) 1.33 M
D) 3.00 M
Show Answer
Answer:
Correct Answer: C
Solution:
Resultant $ [{H^{+}}]= $
$ \frac{M_1V_1+M_2V_2}{V_1+V_2}=\frac{100+100}{150}=1.33M $
