Aqueous Sodium Hydroxide (NaOH) can be used as solvent to help dissolve water insoluble compounds that have an acidic functional group. NaOH reacts with the acidic functional group and forms a water soluble salt.

For example, consider R-COOH to be a water-insoluble carboxylic acid. When R-COOH is added to the aqueous NaOH, the following reaction occurs:

R-COOH + NaOH(aq) -> R-COO- NA+ + OH- + H3O+

The above reaction produces R-COO- NA+ which is a water soluble salt. This process is sometimes called water solubility by salt formation.

What do you get when you dissolve sodium hydroxide in water is it a solute or a solvent?

The solute is the thing that dissolves, in this case the sodium hydroxide. The solvent is the thing that dissolves it, in this case the water. The result is neither solvent nor solute, but a solution. It could be used as a solvent for some other material.


What is the product when dissolve benzoic acid in dichloromethane and add sodium hydroxide?

The solvent (if it is entirely a solvent, as it is in this case) makes no difference. In theory, you would get sodium benzoate, but getting sodium hydroxide to react in a system including an organic solvent will not be easy as it is barely soluble. Vigorous agitation would be required.
