Homework Answers
3) The Ksp would be higher, since the water in the flask dilutes the solution a little more and increases the calculated concentration.
4) The moisture in the filter can dilute the salt being studied and create errors.
If you liked the answer, please rate it in a positive way, you would help me a lot, thank you.

3. Consider the analysis of the ammonia content in this experiment. If the buret used in the titration was rinsed with distilled water, but not dried or conditioned before use, would the calculated number of moles of ammonia per gram of complex be too high, too low, or unaffected? Briefly Explain. If the titration flask was rinsed with distilled water but not dried before use, would the calculated number of moles of ammonia per gram of complex be too high,...

Ksp of Ca(IO3)2 lab questions 1) Why is it necessary to filter the calcium iodate solution through dry filter paper, without adding any water? 2) If water had been added during the filtration process, how would this affect your calculated value for the Ksp of calcium iodate? Clearly explain whether your value would be too high or too low compared to the actual Ksp and why.

answer all parts: 2. You measured the volume of the CO2 by filling your flask with water and tightly inserting the stopper. a. Why was it necessary to tightly stop the water-filled flask and then remove the stopper before you emptied the water into a graduated cylinder for measurement? b. Would your calculated molar volume of CO2 (Vm) have been higher or lower if you had forgotten to stopper the flask before measuring the volume of the flask (V1)? Briefly...

Questions: 1. 495 mg of dried KHP is dissolved in 35 mL of distilled water and titrated with potassium hydroxide (KOH). If it took 22.02 mL of KOH to reach the endpoint, determine the concentration of KOH. Show calculations. If you forgot to dry the above KHP sample and it was later determined to contain 5.00 % water by weight, what would be the actual concentration of the KOH, taking into account the water content? Show calculations. 2. If you...
