Question

100 mL of a 0.1 M HCl solution, 200 mL of a 0.2 M $HN{O}_3$ solution and 200 mL of a 0.5 M NaOH solution were mixed. The resultant solution will be

• A. Acidic
• B. Basic
• C. Neutral
• D. Can't say

Answer 1

The correct option is B Basic

Milliequivalents of $HCl=100\times 0.1\times 1=10$
Milliequivalents of $HN{O}_3=200\times 0.2\times 1=40$
Milliequivalents of $NaOH=200\times 0.5\times 1=100$
Total milliequivalents of the acid = 50
The number of milliequivalents of the base is greater than the number of milliequivalents of the acid.
So, the resultant solution will be basic.
