Because the indicator is unaffected. The indicator will change
colour once the amount of chemical from the burette is added
sufficient to reach an equivalence point. Boiled deionized water
only dilutes the mixture, it doesn't change the amounts of either
reagent.
Ksp is temperature dependant. If you look at the list of Ksp values you should always see a note specifying that these values are determined at 25
Does adding boiled, deionized water to the titrating flask to wash the wall of the erlenmeyer flask and the buret tip increase, decrease, or have no effect on the Ksp value of the Ca(OH)2
Does adding boiled, deionized water to the titrating flask to wash the wall of the Erlenmeyer flask and the buret tip affect the Ksp value of the Ca(OH)2? Explain.
1A) How will the calculated Ksp value of Ca(OH)2 be affected if the original Ca(OH)2 solution is not saturated? Explain? B) Does adding distilled water to the titrating flask in order to wash the sides of the flask and the buret tip affect the computed Ksp of Ca(OH)2? Explain? C) How might tap water instead of distilled water affect the calculated Ksp of Ca(OH)2? Explain? D) The temperature of the solution was 21.1 degrees Celcius. Is the molar solubility of...

Lab Questions 1. Explain what happens to the moles of H" in the flask when you add boiled, deionized water to rinse the wall of the flask during the titration. Explain what happens to the moles of OH' needed from the buret to neutralize the acid after adding the water. What is the overall effect on the calculated acetic acid % of your sample? 2. Suppose that you do not add the water to rinse the wall of the flask,...
how would the results have changed in Ca(OH)2 solution if there had been a trace of acid impurity present in the Erlenmeyer flask you used (We were trying to calculate Ksp when titrating HCl solution, so I guess the results of Ca(oh)2 calculations should change.)
Question 5 1 pts You have a saturated solution of Ca(OH), in a flask, meaning there is some solid Ca(OH), sitting at the bottom of the aqueous solution. Which of the following will increase the Ca2+ concentration in solution? Adding water to the solution. Adding HCl(aq) to the solution. Adding KOH(aq) to the solution Adding more Ca(OH)2(s) to the flask,
please answer these questions below Experiment 7: Titration II volume of deionized water so that(20 mL of solution contains 40 mg of vitamin C. For example, if you have a 500-mg tablet, crush it up and dissolve it entirely in 250 mL of deionized water. Then use 20 mL of that solution for standardization. Is the quantity 20 mL important? What would happen if you used 250 mL? Place the buret in the clamp on the ring stand. Using a...
ALT CHEM 125 Name Determining the Ksp of Calcium Hydroxide Calcium hydroxide is an ionie solid that is sparingly soluble in water. A saturated, aqueous, solution of Ca(OH), is represented in equation form as shown below. Ca(OH)2 (5) --- Ca' (aq) + 2OH(aq) The solubility product expression describes, in mathematical terms, the equilibrium that is established between the solid substance and its dissolved ions in an aqueous system. The equilibrium expression for calcium hydroxide is shown below. Kp - [Ca][OHT...
