Kedu ihe bụ pH?
PH bụ ihe nleba anya nke ọrụ ion hydrogen na ngwọta.Mmiri dị ọcha nke nwere nha nhata nke ion hydrogen dị mma (H +) na
adịghị mmaion hydroxide (OH -) nwere pH na-anọpụ iche.
● Ngwọta nwere nnukwu ion hydrogen (H +) karịa mmiri dị ọcha bụ acidic ma nwee pH na-erughị 7.
● Ngwọta nwere oke ion hydroxide (OH -) karịa mmiri bụ isi (alkaline) ma nwee pH karịrị 7.
