<u>Answer:</u> The solubility equilibrium equation is written below.
<u>Explanation:</u>
Solubility is defined as the maximum amount of solute that can be dissolved in a solvent at equilibrium.
Solubility product is defined as the product of concentration of ions present in a solution each raised to the power its stoichiometric ratio. It is represented as
Calcium lactate is an ionic compound formed by the combination of 1 calcium ion and 2 lactate ions.
The equilibrium reaction for the ionization of calcium lactate follows the equation:
The solubility product for the above reaction is:
Hence, the solubility equilibrium equation is written above.
The principal quantum number is just the first quantum number out of 5. It actually depends on what value of n. See the attached picture for the ordered arrangement of orbitals. For example, when n=2, we have: 2s2p. Each s holds 1 orbital, p has 3 orbitals, d has 5 orbitals and f has 7 orbitals. So, for n=2, there are 4 total orbitals.
