I can't find a substance apart of water with a pH of 7,so i have a question, i don't know if water is the only neutral substance or if there are more which one's are those?
Any salt solution that doesn't hydrolyze in water will be neutral.
Any liquid (alcohol, gasoline, etc) are not ionized and they are neutral. I don't know if this quite addresses your question or not. If not I can try again.
what is hydrolyze?
react with water. For example,
The NH4^+ of NH4Cl reacts with water as follows.
NH4^+ + H2O ==> NH3 + H3O^+
or Na2CO3 the CO3^+2 ion reacts with water.
CO3^-2 + HOH ==> HCO3^- + OH^-
whereas, NaCl, neither cation nor anion react with water.
