unknown acid, which can be either oxalic acid, H2C2O4, or citric acid, H3C6H5O7. To determine which acid she has, she titrates the unknown acid with 0.650 M NaOH. The equivalence point is reached when 52.0 mL are added. Answer the following questions to determine the identity of the unknown acid. 1. How many moles of NaOH are consumed?

A student conducting this experiment measures out 0.913 g of an unknown monoprotic weak acid and dissolves it in 110 mL of water. After adding an indicator, the student titrates the weak acid with 15.55 mL of 0.380 M NaOH to reach the equivalence point. What is the molar mass of the unknown acid?

You are given a solution of HCOOH (formic acid) with an approximate concentration of 0.20 M and you will titrate this with a 0.1105 M NaOH. You add 20.00 mL of HCOOH to the beaker before titrating, and it requires 35.43 mL of NaOH to reach the end point. What is the concentration of the HCOOH solution?

A technician would like to standardize an unknown Ca(OH)2 solution. It takes 22.41 mL of a 0.155 M solution of HCl to titrate 25.00 mL the unknown Ca(OH)2 solution. Calculate the molarity of the Ca(OH)2 solution.  Tip: Don't forget to consider the mole ratio between HCl and Ca(OH)2.

A student is asked to standardize a solution of calcium hydroxide. He weighs out 0.952 g potassium hydrogen phthalate (KHC8H4O4, treat this as a monoprotic acid).It requires 35.7 mL of calcium hydroxide to reach the endpoint.A. What is the molarity of the calcium hydroxide solution?  This calcium hydroxide solution is then used to titrate an unknown solution of nitric acid.B. If 15.6 mL of the calcium hydroxide solution is required to neutralize 29.1 mL of nitric acid, what is the molarity of the nitric acid solution?

A student is given 1.52 g of an unknown acid, which can be either oxalic acid, H2C2O4, or citric acid, H3C6H5O7. To determine which acid she has, she titrates the unknown acid with 0.650 M NaOH. The equivalence point is reached when 52.0 mL are added. Answer the following questions to determine the identity of the unknown acid. 1. How many moles of NaOH are consumed? Moles of NaOH = _____ mol 2. How many moles of H+ acid are available to react if the acid is H2C2O4? 0.0403 mol NaOH Moles of H+ from H2C2O4 = ___ mol 3. How many moles of H+ are available to react if the acid is H3C6H5O7? 0.0403 mol NaOH 0.0573 mol H+ from H2C2O4 Moles of H+ from H3C6H5O7 =  ___ mol

To increase the acidity of soil, you can add peat, which contains a complex acid mixture known as humic acid, a diprotic acid (two acidic protons). The complexity of the humic acid makes it difficult to determine how acidic you are making the soil. You decide to use a titration to get a better measure. If a titration of an unknown sample of humic acid required 3.68 mmols of NaOH, how many mmols of humic acid were present in the unknown sample?
