The soapy precipitate is the salt of a weak base. Addition of HCl will generate the free fatty acid which can then be neutralized by NaOH. The difference in the number of moles of HCl and NaOH required to reach the endpoint gives the number of moles of RCO2 which can then be used to calculate the mass present in the solid and the percentage of the metal content.
