What is the emf of a cell consisting of a Pb^2+ / Pb half-cell and a Pt/H+/ H2 half-cell if [Pb2+] = 0.53M, [H+]= 0.086M and PH2= 1.0atm

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.
