It requires determining the volume of a 0.1 M monobasic strong acid necessary to neutralize 0.1 g of Fe(OH)3 and calculating the resulting pH of the solution. The solution involves understanding the reaction between the acid and the hydroxide, leading to the conclusion that 30.09 cm\u00b3 of acid is needed, resulting in a pH of 2.69."}
