3a) A student determines the concentration of a sodium hydroxide solution by titration with standardized KHP. S/he obtains the values: 0.190 M, 0.202 M, and 0.205 M. Should the value 0.190 M be rejected? Apply the Q Test. For three values Q must be greater than 0.94 to reject the number. Q = suspect nearest | largest - - smallest b) The student de to repeat the experiment two more The five values now include: 0.190 M, 0.202 M, 0.205 M, 0.201M and 0.203M. Use the Q Test to see if the first value may be rejected. For five values Q must be greater than 0.64 to reject the number. c) Solve for the average Molarity of the measurements from part b with and without the rejected number. Is there value in repeating an experiment several times?

The strong acid HI is added to 0.1 M/0.1M CH3COOH/CH3COONa. What is the full reaction equation, full ionic equation, and net ionic equation for the reaction that will occur? Thank you so much im really lost.
A 250 ml solution is prepared with 1.5 g KCI salt and a 50 ml sample is taken from it. Over 40 ml 0,1100 N AGNO3 is being added. After AgCl is filtered off, it is titrated with KSCN with Fe (III) indicator. Since 5 ml of 0,1N KSCN is spent in the titration, can we find the amount of KCI and the percentage of KCI purity? (K. 39 g/ mol, CI: 35.5 g/mol)
Will adding water to SbCl + H20 <----> SbOCl + 2HCl form more or less precipitate? Will adding hydrochloric acid to SbCl + H20 <----> SbOCl + 2HCl form more or less precipitate?
4. In an experiment to determine the concentration of an HCI sample of unknown concentration, 0.1 M NaOH solution was prepared in the first step. Then, 50 mL of NaOH prepared as 0.1 M and 5 drops of methylorange indicator were added to a 250 mL flask and titrated with H2C204 prepared as 0.05 M. The turning point was observed when 26 mL of H2C204 was consumed in the titration process. In the second step, 50 mL of a non-concentrated HCI solution and 5 drops of phenolphthalein solution were added to a 250 mL flask and titrated with the adjusted NaOH solution. Calculate the concentration of an HCI sample with an unknown concentration, since it is determined that 16 mL of NaOH solution was consumed after titration.

Suppose you have a solution that might contain any or allof the following cations: Ni2+, Ag+, Sr2+, and Mn2+. Additionof HCl solution causes a precipitate to form. After filteringoff the precipitate, H2SO4 solution is added to the resultingsolution and another precipitate forms. This is filtered off,and a solution of NaOH is added to the resulting solution.No precipitate is observed. Which ions are present in each ofthe precipitates? Which of the four ions listed above must beabsent from the original solution?
