This round I learn a lot about PH, so PH is the balance of Acid and Base. An Acid is an ionic compound that produces positive hydrogen ions (H+) when dissolved in water. A Base is an ionic compound that produces negative hydroxide ions (OH–) when dissolved in water.
Acid = HCl−→−H2OH++Cl−
Base = NaOH−→−H2OOH−+Na+
PH are important because many living thing, Example many plant grow best in soil that has a PH between 6 and 7. fish also need a PH close to 7. the neutral of PH is around 7 to 7.5, water is neutral has a PH of 7.
