Suppose that you are performing a titration of a hydrochloric acid solution of unknown concentration using a standardized solution of 0.063 M Ca(OH)₂. You prepare the analyte solution by adding 10.0 mL of the unknown hydrochloric acid solution, 40.0 mL of water, and 2 drops of phenolphthalein to an Erlenmeyer flask. You discover that it takes 37.05 mL of Ca(OH)₂ to reach the end point. What is the concentration of the unknown HCl solution? HCl concentration: M
4. A student did not read the directions to the experiment properly and mixed up where to put the NaOH and the HCl solutions. He put the HCl in the buret and the NaOH in the flask. He then added a drop of the phenolphthalein to the solution in the flask. Does the student need to empty out all of the solutions and start over again or can he go ahead and run the titration?

The flask contains 10.0 mL of HCl and a few drops of phenolphthalein indicator. The buret contains 0.280 M NaOH. It requires 17.9 mL of the NaOH solution to reach the end point of the titration. What is the initial concentration of HCl? concentration: М НСІ
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?
A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 51 mg of oxalic acid (H2C2O4), a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250 mL of distilled water. The student then titrates the oxalic acid solution with her sodium hydroxide solution. When the titration reaches the equivalence point, the student finds she has used 19.2 mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution.
A science teacher needs to determine the concentration of an old, unmarked bottle of hydrochloric acid. She prepares a base titrant by dissolving 40.0 g of potassium hydroxide in 500.0 mL of water. The base is pipetted into a 28.00 mL sample of the acid, which also contains phenolphthalein as an indicator. The solution turns from clear to pink after the addition of 7.34 mL of base. What is the concentration of the hydrochloric acid?

You are running an acid-base titration with hydrochloric acid and calcium hydroxide. The calcium hydroxide is your titrant; it has a known concentration of 0.0891 M. You have added 25.0 mL of the hydrochloric acid solution to an Erlenmeyer flask along with 2 drops of phenolphthalein (fee’-nol-thay-leen) indicator. To begin your first trial, you fill a clean 50 mL buret with the calcium hydroxide solution. Your starting volume is 0.25 mL. After the addition of solution from the buret, you see a color change in the flask, and the end point of the reaction is reached. You note the final volume in the buret to be 18.75 mL. You begin again for your second titration trial. You add 24.8 mL of the hydrochloric acid solution to a clean flask along with 2 drops of indicator. You refill the buret to an initial volume of 1.42 mL. When the reaction is complete, you note the final volume in the buret at 16.74 mL. Then you complete a third trial. You add 25.6 mL of hydrochloric acid solution…
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?

The iodine contained in every one mL of the 0.010 M iodine solution in the buret will react with 1.76 mg of vitamin C. (In other words, every mL of iodine solution needed for the titration indicates the presence of 1.76 mg of vitamin C in the juice sample.) If your titration used 5.86 mL of iodine solution, what mass of vitamin C is in your fruit juice sample (in milligrams, mg)?
