How to calculate the % by mass? « on: January 31, 2013, 01:08:55 AM » Hello everyone.I'm doing my lab and I am having difficulty calculating the % of acetic acid (by mass). The question says using the provided molarity(0.298M) of the NaOH solution, calculate the % of aceti...
In a titration of a sample of HCl(aq) with 0.113 M NaOH(aq), it took 51.2 mL of the base to reach the endpoint of the titration. Calculate the number of moles of the acid being neutralized. How do you prepare phenolphthalein indicator for titration? How do you find molarity of vinegar...
You can calculate the percentage of ionization of an acid given its pH in the following way: Step 1: Convert pH to [H+] pH is defined as -log [H+], where [H+] is the concentration of protons in solution in moles per liter, i.e., its molarity. If, for example, you have a 0...
1.12 g of KHP required 34.38 mL of an approximately 0.3 m NaOH solution in an acid/base titration to reach the equivalence point. What is the exact molarity of the NaOH solution? The equivalence point is the point in a titration at which the added...
