Consider the cell Pt |Cr2+(aq, 1.0 M), Cr3+(aq, 2.2 mM) || Pb2+(aq, 1.3M)| Pb. What is the actual cell potential (E) at 298 K for this cell ?

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.

the answer is a for sure mark brainliest i had got this right on usatestprep
