Question

the reaction NaOH + H2O is a/an ______ reaction................ 1.reduction , 2.exothermic , 3.endothermic , 4.oxidation ?????​

Answer 1

Answer:

2. exothermic

Explanation:

The process of diluting an acid or a base in water is very exothermic. Care must be taken while diluting an acid or base.

The acid or base must be slowly added to water with constant stirring.

Don't add water to acid or base. Such a reaction may be so exothermic that the mixture may splash out and the test-tube may break due to excessive local heating.

The reaction is as below:

NaOH + H₂O -------> Na⁺ + OH⁻

Answer 2

Answer:

exothermic is correct answer ......
