A student dilutes 50 mL of a phosphoric acid-dihydrogen phosphate buffer solution to a final volume of 100 ml. Will the pH of the buffer change noticeably? (Use Henderson -Hasselbeck conceptually ) For the same dilution above will the buffer capacity change ? Calculations: A 50.0 mL sample of a 0.100 M phosphoric acid, H3PO4 is titrated with 0.100 M NaOH. Identify the major chemical species present and calculate the pH at these four points (first consider the titration curve)...

•A 25.00 mL volume of commercial hydrogen peroxide (H2O2) solution was diluted to 250.0 mL in a volumetric flask. Then 25.00 mL of the diluted solution were mixed with 200 mL of water and 20 mL of H2SO4 and titrated with 0.02123 M KMnO4. The first pink color was observed with 27.66 mL of titrant. A blank prepared from water in place of H2O2 required 0.04 mL to give visible pink color. Find the molarity of the commercial H2O2.
