From the given options, let's select the correct Answer choice.
An acid can be said to be any substance containing hydrogen which can be able to donate hydrogen ions to another substance.
An acid does not feel slippery, rather it just feels wet. It is a base that is slippery.
An acid has a lower pH when compared to a base. pH less than 7 indicates acidity while pH greater than 7 indicates a base.
When an acid is added to water, the hydroxide ion concentration will reduce and the pH of yhe solution increases towards 7.
Therefore, an acid decreases the amount of ions in a water solution.
ANSWER:
a). Decreases the amount of ions in a water solution.
