Calculate the moles of naoh used
WebSo the mole ratio NaOH:H 2 SO 4 is 2:1. Therefore 0.00750 mol of NaOH reacts with (0.00750 ÷ 2) = 0.00375 mol of H 2 SO 4 Step 3: Calculate the volume of sulfuric acid WebMar 27, 2024 · We also know that #NaOH# is a monoprotic base, because there's only one #OH^-# ion in its chemical formula. Therefore, #1# mole of #KHP# will correspond to #1# mole of #NaOH# in a neutralisation reaction. In other words, #1# mole of #NaOH# will neutralise #1# mole of #KHP#. The number of moles of #KHP# that was neutralised was:
