2) During an investigation, a student tested three samples of the same solution with three different indicators and the results of which are shown below A. The student determined the pH of the sample to be B. Use the following information to answer the nex C. D. Bromocresol green-blue Chlorophenol red-red Phenolphthalein-colourless less than 3.8 between 5.2 and 6.8 between 6.8 and 8.2 greater than 10
5. In a titration, a student finds that 14.0 mL of KOH(aq) are required to neutralize 0.93 g KHC H,O,(5) KOH(aq) + KHC,H,O,(s) HOH(aq) + K,C₂H₂O₂ (s) The concentration of KOH(aq) is 0.000 33 mol/L 0.064 mol/L 0.33 mol/L 3.1 mol/L A. B. C. D. When 100 mL of Kl(aq) is mixed with 200 mL of Pb(NO,),(aq) a reaction occurs. A test that could be performed to identify the excess reagent would be to A. Use the following information to answer the next question B. C. D. add NaNO, (aq), if a precipitate forms Kl(aq) is in excess, if not Pb(NO₂)₂(aq) is in excess. add NaNO,(aq), if a precipitate forms Pb(NO,),(aq) is in excess, if not Kl(aq) is in excess. add Nal(aq), if a precipitate forms Kl(aq) is in excess, if not Pb(NO₂),(aq) is in excess. add Nal(aq), if a precipitate forms Pb(NO,),(aq) is in excess, if not Kl(aq) is in excess.
