You titrate 0.500 g of an unknown monoprotic acid with 0.0990 M NaOH. You discover that it takes 23.56 ml of base to completely neutralize the acid. what is the formula weight of the unknown acid? If the unknown were a triprotic acid, what would its formula weight be?
Please help with my Titration lab! I am having difficulty
understanding this. Thank you!
C. Analyzing an unknown base - optimizing a method: In this segment you will design your own method for analyzing an unknown base. In the solutions list there are several different concentrations of HCl to choose from. You can also try different sample volumes of the unknown base. Be sure to record these for each trial. Your goal is to find two different combinations of HCI...
In this experiment, you will titrate an unknown acid with a base. It will be important for you to understand certain things about this titration in order to identify successfully your unknown. For all of the following questions, assume you are titrating an unknown monoprotic acid, HA, with NaOH solution. 0.146 g of HA is added to a beaker and made into a solution with ~100 mL of distilled water. As the titration proceeds, you keep track of the pH...
If the 20mL of 0.125 M NaOH is required to titrate 10mL of an acid unknown concentration to reach the equivalence point, then find the concentration(molarity) of the unknown acid.

2. Suppose that you used a known concentration (0.8442 M) of Ca(OH)2 to determine the concentration of an unknown HBr solution. If it takes 12.88 mL of the Ca(OH)2 solution to titrate 15.00 mL of the unknown HBr solution, what is the molarity of the HBr? 1. A solid diprotic weak acid, H2A (molecular weight = 128.9 g/mol) is used to standardize a KOH solution. When 0.4228 g of the acid is dissolved in 40.0 mL of water...

35.25 mL of NaOH solution are required to titrate 0.5745 g of an unknown monoprotic acid. Prior standardization of the NaOH determined its concentration as 0.1039 M. 1. Use the data provided to determine the molar mass of the unknown acid 2. If 20 mL of a 1.0 M solution of the unknown monoprotic acid is placed into a beaker and 10 mL of 0.1 M NaOH is added, the pH of the final solution is 1.9. What is the...
