Web14 aug. 2024 · The ions from the salt crystal are said to be hydrated. If the stability that hydration gives the ions in solution is greater than the stability of the crystal lattice, then the salt will dissolve. Sodium chloride is a familiar example of a soluble salt. WebFor ionic compounds you have to balance the charge of each part by multiplying each ion until the sum of the charges = 0; Example: what is the formula of aluminium sulfate? Write out the formulae of each ion, including their charges; Al 3+ SO 4 2-Balance the charges by multiplying them out: Al 3+ x 2 = +6 and SO 4 2- x 3 = -6; so +6 – 6 = 0
