8. Based on equation #1 for the reaction of HCl with NaOH, if the HCl concentration is increased from 0.1M to 0.2M, how will this affect the amount of NaOH (base) required for complete neutralization? A. Has no effect B. The amount of base required will double C. The amount of base required is reduced by one-half D. Cannot determine from this data E. Amount of base required is decreased by a factor of ten 9. Which equation below is correct for the reaction of stomach acid (dilute HCl ) with Milk of Magnesia (Mg(OH)2) ? A. 2HCl+Mg(OH)22H2O+MgCl B. HCl+Mg(OH)2H2O+MgCl2 C. HCl+Mg(OH)2H2O+MgCl D. 2HCl+Mg(OH)22H2O+MgCl2 E. None of the answers are correct 10. Based on the amount of titrant (from the buret) used in Equation #1 (shown below), if the titration endpoint is missed and the solution is too pink, the results calculated will be A. Artificially too high B. Artificially too low C. Unaffected by solution color D. Inaccurate, but could be too high or too low, depending upon reaction conditions E.
