For example sodium tetradecyl sulfate.
Sodium sulfate solution is neutral; the red litmus is purple.
Sodium sulfate is soluble in water. Hydrochloric acid is a water solution of HCl. Solubility is considered a physical property.
The water solution of magnesium sulfate is not acidic.

It give out heat (exothermic) and you get yourselves solution of sodium sulfate salt and water.
Sodium sulfate dissolves in water to produce a solution of sodium sulfate.
Sodium sulfate is highly soluble in water, but insoluble in most organic solvents. If you want to increase its solubility in water (as for any salt), you can heat the solution or remove one of the products (sodium ions or sulfate ions) from solution. I can't think of any insoluble sodium salts, but barium sulfate (BaSO4) is insoluble in water. Thus, adding barium chloride (or some other soluble barium salt) will remove sulfate from the equilibrium (due to BaSO4 precipitation) and increase the solubility of sodium sulfate.

No. Sodium lauryl sulfate will not form insoluble salts with the magnesium.
At 20 oC the maximal solubility of sodium sulfate is 40,8 g/L.
