Incorrect statement about pH and H+ is:
1. | pH of neutral water is not zero. |
2. | Adding 1M solution of CH3COOH and 1M solution of NaOH, the pH will be 7. |
3. | H+ of dilute and hot H2SO4 is more than concentrate and cold H2SO4 |
4. | Mixing solution of CH3COOH and HCl, pH will be less than 7 |
