For the following Assertion and Reason, the correct option is : Assertion : The pH of water increase with increase in temperature. Reason : The dissociation of water into H+ and OH- is an exothermic reaction
- Assertion is not true, but reason is true
- Both assertion and reason are false
- Assertion is true but reason is not the correct explanation for the assertion
- Both assertion and reason are true, and the reason is the correct explanation for the assertion
Correct answer: Both assertion and reason are false
Solution
The assertion is incorrect because the pH of water actually decreases with an increase in temperature, as higher temperatures lead to greater dissociation of water into H+ and OH- ions. The reason is also false because the dissociation of water is an endothermic process, not exothermic.
