salicylic acid is the sublimate, the residue is the sodium sulfate
nickel sulfate + sodium carbonate -> sodium sulfate + nickel carbonate
According to me, Sulfur trioxide (SO3) can replace chlorosulfonic acid to prepare sodium lauryl sulfate.
Most acids will not react with sulfates as the sulfate ion (SO42-) is a very weak base. However, a strong acid will react with a sulfate ion tor form a bisulfate ion (HSO4-). Here is an example with hydrochloric acid and sodium sulfate. HCl + Na2SO4 --> NaCl + NaHSO4 The products are sodium chloride and sodium bisulfate.
The preferred modern name for the compound with the formula NaHSO4.H2O is "sodium acid sulfate monohydrate". This compound was formerly called "sodium bisulfate monohydrate", and some chemists still use the older name.
It is a salt, which is weakly basic.
You can turn sodium hydroxide into sodium salicylate by reacting it with salicylic acid.

nickel sulfate + sodium carbonate -> sodium sulfate + nickel carbonate
The reactions of sodium hydroxide and calcium hydroxide with sulfuric acid will produce sodium sulfate and calcium sulfate respectively (water will be another product in both reactions. Sodium sulfate is soluble in water and so will remain in solution. Calcium sulfate, however, is insoluble and will precipitate as a solid.
It is an acid salt.

Sodium hydroxide (strong base) and Sulphuric acid (strong acid)
Sodium hydroxide in a pure form is a solid, so you cannot dissolve anything in it. Normally, NaOH is used as an aqueous solution. But salicylic acid dissolves in water, so the presence of NaOH in the water is irrelevant to the solubility of salicylic acid. It is the water, not the NaOH, that dissolves the salicylic acid.
Sodium sulfate is soluble in water. Hydrochloric acid is a water solution of HCl. Solubility is considered a physical property.
