Gathered materials to compete the lab.

Place 10 mL of 1.0 HCl in beaker and add 90 mL water and use the pH meter (Station) measure pH of solution

Put a magnetic stir in beaker, and place one or two pieces into solution until the pH is 3.5

Measure the mass of of the remaining metal and determine the molar mass of the unknown metal with the given formula

For part B add 10 mL of unknown solution (0.05) and add 20 mL of water, 5 drops of indicator, magnetic stir

Use the pH meter for after completing previous step

Over the course of the experiment, my group was able to discover what exactly what were the unknown metals were. In order to do that we had to complete the steps for each part and eventually calculate what the molar masses were for each part in order to correctly determine what the metals were. Continuing, we also noticed that part A and B differed in terms of what the unknown metals turned out to be for each one. Part A's unknown metal eventually was found to be beryllium, while part B's unknown metal was determined to be Barium. In closing, after following the steps and performing the calculations using the formulas we were able to determine that the two unknown metals were Beryllium and
