If 21.88 ml. of a solution of Ba(OH)2 requires 18.68 ml. of a 2.893 M solution of HNO3 for
complete titration. what is the molarity of the
Ba(OH)2 solution?
Answer in units of M.

- lead + phosphoric acid = hydrogen + lead(ii) phosphate

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.
