Water _____.
Sergio039 [100]

Answer: is neither an acid nor a base

Explanation: Water is a universal solvent which means it can dissolve most of the substances in it.

Water has high thermal heat capacity , which means large heat is required to heat the water.

Water is not always pure as it gets contaminated by various pollutants present in the atmosphere such as gases, bacteria and suspended matter.

Water is an amphoteric substance which can act as both acid and base, thus can donate and acept [texH^+[/tex] ions.Thus it is neither an acid nor a base.

HCl+H_2O\rightarrow H_3O^++Cl^-

Here water is accepting a proton, thus it acts as base.

NH_3+H_2O\rightarrow NH_4^++OH^-

Here water is donating a proton, thus it acts as acid.
