Please help me with 6a calculations Experimental Procedure, Part A.6 versus Part B.2. Would you expect more or less standard 0.05 M HCI to be used to reach the methyl orange endpoint in Part B.2? Explain. A determination of the molar solubility and the K_sp calcium hydroxide was completed according to the experimental procedure. The following data were collected for Trial 1. (See Report Sheet.) Complete the table for the determinations. Record the calculated values to the correct number of...

Calculate the concentration of the standard HCl solution you prepared. Determine this concentration for each trial and the average and standard deviation for all three trials. Part B-Preparation and standardization of an HCl Solution 1. Before you can titrate your saturated Ca(oH)a solutions, you must prepare and standardize a dilute solution of Hcl. With a graduated cylinder measure at least 6 mL of the stock Hcl lution, transfer it to a 125 mL Erlenmeyer, and dilute to approximately 100 mL...
I need help filling out the “Q-Test Determination” as well as the “Post-Lab Questions” The directions are in the first three pictures, and the questions I need answered are in the last two pictures. Thanks. O-Test Datum Rejection We may be in a situation where one data value apparently has a strong influence on the mean of a set of data Assume we have 6 data points to analyze to be sure that each point is a viable part of...
