Find the potential at the sodium ion, Na+, which is surrounded by two chloride ions, Clˆ’, and a calcium ion, Ca2+, in water as shown in the diagram. The effective charge of the positive sodium ion in water is 2.0 × 10ˆ’21 C, of the negative chlorine ion is ˆ’ 2.0 × 10ˆ’21 C, and of the positive calcium ion is 4.0 × 10ˆ’21 C.
