Question

1) An Acid or a base mixed
with water. Is this process exothermie
or endothermie ? Explain briefly? ​

Answer 1

Explanation:

Adding water to an acid or base will change its pH. Water is mostly water molecules so adding water to an acid or base reduces the concentration of ions in the solution. ... The acid is becoming less acidic. Similarly, when an alkali is diluted with water the concentration of OH - ions decreases.
