Abstract
The present invention provides a method for producing an aqueous tin methanesulfonate solution by dissolving tin (II) oxide in an aqueous methanesulfonic acid solution, wherein if A is the number of moles of the tin (II) oxide and B is the number of moles of the methanesulfonic acid, the value of B/2A is within the range of from 1.0 to 1.4. This method for dissolving tin (II) oxide into an aqueous methanesulfonic acid solution is able to achieve a high tin ion concentration.
