MCQ
When $100 \,ml$ of $1\,M$ $NaOH$ solution is mixed with $ 10 \,ml$ of $10\, M$ ${H_2}S{O_4},$ the resulting mixture will be
- ✓Acidic
- BAlkaline
- CNeutral
- DStrongly alkaline
✓
Answer
Correct option: A.
Acidic
(a) ${N_{NaOH}} = 1 \times 1 = 1\,N$
${N_{{H_2}S{O_4}}} = 2 \times 10 = 20\,N$
M.eq. of $NaOH$ $ = 1 \times 100 = 100$
M.eq. of ${H_2}SO4 = 20 \times 10 = 200$
Thus M.eq. of acid are left and therefore $pH< 7$ , so the resulting mixture will be acidic.
