How to calculate the mass percent of acetic acid in vinegar. Calculate the pH of a solution prepared by dissolving 2.20 g of sodium acetate, CH3COONa, in 74.5 mL of 0.20 M acetic acid. (Ka of CH3COOH is 1.75 x 10^-5) Calculate the pH of a buffer with different moles of a weak a...
Calculate the theoretical amount of 0.5 M NaOH that it would take to neutralize approximately 2.0 g KHP. KHP is a monoprotic acid, the molar mass of KHP = 204.22 g/mol, and the molar mass of NaOH = 40.00 g/mol. How do you prepare 2 liters of a 0.1 ...
Calculate the mass percent of a solution that is prepared by adding 60.4 g of NaOH to 407 g of H2O. How to do a titration. Write a procedure for how to find the concentration of an unknown monoprotic acid using a sample of 5 mL. Describe what equipment to use and how to set it...
Is it possible to determine whether or not an unknown is mono/di/triprotic with a titration? Why or why not? Is there an equation to find mass percent if you know the concentration and the final and initial volume of a titration lab? If there isn't one, then how do you find m...
Suppose 14.48 mL of 1.161 M HC2H3O2 solution is diluted to 59.37 mL. How many moles of HC2H3O2 are in this solution? Dilution of Solution: A simple solution is prepared by dissolving a single solute species in a single liquid solvent species. The...
Systematic errors may result due to improper calibration of the instruments while random errors cannot be easily detected. Answer and Explanation:1 (a) The errors that are noted when a standardization or titration is conducted are described b...
How many mL of 6M NaOH would be required to neutralize 1 mL of stock sulfuric acid (assume the stock percent assay is 98%)? Find the mass of sodium formate that must be dissolved in 150.0 cm^3 of a 0.50 M solution of formic acid...
What is the rule to find the percent error in the experiment? Explain why an experiment determined the charges on the oxygen atoms in ozone to be 1/2 for its terminal oxygen atoms and +1 for its central oxygen atom. H...
