Question

3. Calculate the molar concentration of an NOH us that required 15.81 ml to com pletely neutralise 0.509 g of KHP (Remember that the "pin KHP does not mean phos phorus. See the molecular structure and molar miss of KHP given earlier in the lab KHP(s) + NaOH(aq) NaKP(aq) + H,O(0) AGAGACOOOOOOOOOOOOOAAAA 4. Calculate the mass of KHP that will react completely with 25.00 mL of 0.1750 M NaOH. 5. Write the balanced equation for the reaction that occurs when aqueous HCl is added to solid Caco, and the solution is heated. 6. Calculate the mass of solid NaOH needed to prepare 250.0 mL of 0.1000 M NaOH solu- tion. Lab 11
