Which relationship is present in a solution that has a pH of 7? 1) [H+] = [OH-] 3) [H+} < [OH-]
2) [H+] > [OH-] 4) [H+] + [OH] = 7

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
