[Answer in not more than 3 sentences]Topic: Standardization of acid and base with back titration Note: Include up to 4 decimal places Kindly explain the process Thank you!Situation: A 0.1214-g sample of impure Na2CO3 was analyzed by the Volhard method. After adding 50.00 mL of 0.07011 M AgNO3, the sample was back titrated with 0.06021 M KSCN, requiring 27.15 mL to reach the end point. Questions: ONLY answer NUMBERS 3 and 4 Write the net ionic equations involved of the above titration process. Calculate the purity of the Na2CO3 sample based on the given above. The Ksp of AgCl is 1.82 x10-10 and the Ksp of AgSCN is 1.1 x10-12. Calculate the molar solubility of each express as mol Ag+/ L. What precipitate is more soluble? Is there a problem with this with reference to the titration above? And if there is, how will you remedy this?
- 40.00 mL of unknown calcium hydroxide solution is titrated with 0.200 M standard nitric acid solution. If 41.60 mL of the standard acid solution is required to reach a phenolphthalein endpoint, what is the molarity of the unknown calcium hydroxide solution? (Hint: write the balanced formula unit equation.)Review the list of common titration errors. Determine whether each error would cause the calculation for moles of analyte to be too high, too low, or have no effect. ANSWER BANK: Too low, No effect OR Too high adding titrant past the color change of the analyte solutionrecording the molarity of titrant as 0.1 M rather than its actual value of 0.01 Mspilling some analyte out of the flask during the titrationstarting the titration with air bubbles in the buretfilling the buret above the 0.0 mL volume markData Table 2: Complexometric Titration of Tap Water photo shows equation to find water hardness 6 ml of water used (5 ml of tap water 1ml of buffer) Hard Water Trial 1 Hard Water Trial 2 Hard Water Trial 3 Initial Syringe Reading (mL) 2ml 2ml 2ml Final Syringe Reading (mL) .61ml .69ml .58ml Volume of EDTA Consumed (mL) 139ml 131ml 142ml Water Hardness ppm CaCO3 (mg/L) Average ppm CaCO3 (mg/L):
