- one or more answers Which of the following will result in an increase in the calculated Ksp of Ca(OH)2? Receiving flask used during filtration was contaminated with HCl The Na2CO3 primary standard solution was overtitrated The saturated Ca(OH)2 solution was overtitrated Some Ca(OH)2 solid passed through the filter paper during filtration The water used to dissolve Ca(OH)2 solid was greater than the required amountCHOICES: Increase, Decrease, No Effect and WHY 1. The actual concentration of the sodium hydroxide used in the calibration part of the experiment was lower than the stated value. However, the NaOH solution used in the determination of ΔHrxn was of the correct concentration. [magnitude of ΔHrxn] 2. The test tube used in the determination of the ΔHrxn for nitric acid was still wet with water. [ magnitude of ΔHrxn] 3. The actual concentration of the sodium hydroxide used in the calibration part of the experiment was lower than the stated value. [Ccal] 4. A wet pipette was used to transfer 10.00 mL of 1M HNO3 in the determination of ΔHrxn. [magnitude of ΔHrxn] 5. The thermometer and stopper were inserted to the test tube 5 minutes after adding the base in the calibration part. [Ccal]4) How would your calculated value of Kup be affected by errors introduced from the following sources? Be specific in your answer. State whether Ksp would be too large, too small, or not affected, and explain why that error would have that effect on Ksp c. Although the KIOs used to standardize the Na2S20s is labeled as 0.0100 M, its actual concentration is somewhat higher than 0.0100 M. d. Extraneous water is introduced from wet filter paper or wet funnels, or by washing the precipitate during the final filtration of Ca(IOs)2.
- Given the Ksp for Ag2CrO4 is equal to 1.20 x 10-12, calculate the percent error in your experimentally determined value for average Ksp (this will be an extremely large percentage – think about why).this is the gc from an experiment we did for the extraction of eugenol from clove oil. i just need the chemical compound associated with each peak labeled. thank you. A flowchart of the experiment is included as well. Thank you.How to find the 'K" value using the date in the tables for experiments 1-4
