Homework Answers
| solution | initial components | initial type | change | effect of change on pH |
| A | H2O | neutral | add KCl | pH the same |
| B | H2O, NaOH | basic | add NaClO4 | pH the same |
| C | H2O, NaOH | basic | add HClO4 | pH lower |
| D | H2O | neutral | add KOH | pH higher |
Explanation
A solution which consists of only water is a pH neutral solution.
A solution which consists of water and NaOH is basic solution because NaOH will dissociate and OH- ions will increase the pH.
KCl and NaClO4 salts are neutral salts and will not effect the pH of solution.
HClO4 is a very strong acid and decreases the pH of solution.
KOH is a very strong base and increases the pH of solution.
