.
Acids have a higher concentration of free H+ than are found in bases
Explanation:
Water is also called universal solvent because it can dissolve a large number of polar compounds due to its polar nature. In water, covalent bond is present between hydrogen and oxygen due to which partial positive charge occurs on hydrogen and partial negative charge appears on oxygen atom due to difference in electronegativity values. Acids has high concentration of proton (H+) while bases has high amount of OH- ions.
