1. If the base buret were not rinsed with NaOH prior to filling, would the calculated normality of the base be TOO HIGH, TOO LOW, OR UNAFFECTED? WHY?
2. If the vinegar buret tip were not filled with solution before its initial reading was taken, would the calculated normality of the acid be TOO HIGH, TOO LOW, ORUNAFFECTED? WHY?
3. The active ingredient in Philips Milk of Magnesia is Mg(OH)2, in Amphojel is Al(OH)3; and in Aka-Seltzer is NaHCO3. Write balanced net ionic equations showing how each neutralizes stomach acid. (You can answer this question because it is a review of the "IonicChemical Equations" lab you did in Chem 1 A)
