8. A student adds 22.36 mL of 1.366 x 10¹ M Mg(OH), in order to completely neutralize 25.00 mL of H₂PO acid. Calculate the original concentration of the acid solution.

The dilution equation, rearranged to solve for ?1 is   ?1=?2?2?1 where ?1 and ?1 are the initial concentration and volume, respectively, and ?2 and ?2 represent the final concentration and volume, respectively. A student needs to prepare 50.0 mL of 1.10 M aqueous H2O2 solution from 4.8 M H2O2 stock solution. Set up an equation to solve for the volume of stock solution needed by plugging the given values into the equation.

sentences. 3. Virtual Lab Questions a. A student prepares a solution of hydrochloric acid that is approximately 0.1 M and wishes to determine its exact concentration. A 25.00 mL portion of the HCI solution is transferred to a flask, and after a few drops of indicator are added, the HCI solution is titrated with 0.07575 M NaOH solution. The titration requires exactly 38.92 mL of the standard NaOH solution to reach the end point. What is the molarity of the HCI solution? b. It takes 46.22 mL of a 1.021 M NaOH solution to neutralize a solution of 4.4567 g of an unknown monoprotic acid in 80.00 mL of water. Calculate the molecular weight of the acid. 4(D) 5
