Sulfamic acid (HSO3NH2,97.10 g/mol) is a primary acid that can be used instead of KHP,the reaction with HSO3NH2 with NaOh is as follows HSO3NH2(aq)+NaOH->NaSO3NH2(aq)+H2O(l)
Write the net ionic equation for this reaction. (Include states-of-matter under the given conditions in your answer. Use the lowest possible whole number coefficients.)
