A possible source of systematic error is failure to dry KHP. If this occurred, would the final weight % of Na2CO3 be falsely high, falsely low, or unaffected? How will failure to dry the KHP affect the molarity of the NaOH and HCl solution?
This is referring to an experiment where KHP is used to standardize and NaOH solution and the NaOH solution is used to standardize a HCl solution.The HCl solution is then used to titrate against a soda ash unknown to determine the weight % of Na2CO3.
calculate the pH of the solution that results from adding 8.50ml of 0.100M NaOH to 50.00 mL of a 0.0500M solution of acetic acid.
