MCQ
Which of the following solutions has the highest $pH$ ?
- A$0.2\, M \,HClO_4$
- B$0.20 \,M \,CH_3COOH$
- C$0.020\, M \,HCl$
- ✓$0.2\, M \,NaCl$
✓
Answer
Correct option: D.
$0.2\, M \,NaCl$
d
Apart from $NaCl$, all other are acid so they will have $pH$ less than $7$ but $NaCl$ is salt so it has $pH =7$.
