Please explain in detail
You are going to standardize a 0.80% solution of sodium hydroxide solution for which the molarity is approx 0.20M. You will have dry succinic acid (H2C4H4O4) , a 250 mL volumetric flask, a 25.00mL pipet, a 50.00mL buret, a phenolphthalein indicator solution, and other standard lab equipment. For each titration you will withdraw a 25.00mL sample of the succinic acid solution with a volumetric pipet. Therefore you will deliver exactly one-tenth of your initial mass of succinic acid (to four significant figures) in each titration. In deciding the amount of succinic acid to weigh, assume that you will be using approximately 15mL of the sodium hydroxide of approximate 0.20M concentration for each titration, and you will need enough succinic acid for ten titrations. Show how to calculate the mass of succinic acid you will need to weigh.

Preparation of Sodium Hydroxide Titrant: Prepare 500 mL of a 0.1 M sodium hydroxide solution by dilution of a 1 M sodium hydroxide stock reagent or from solid NaOH. This dilution need only be performed to 5% accuracy, that is, using a graduated cylinder and an Erlenmeyer flask. Store the diluted solution in a polyethylene bottle. Standardize the diluted solution against dry, solid KHP (potassium hydrogen phthalate) using phenolphthalein as an indicator and label the bottle with the concentration of...

1. Your boss asks you to prepare and then standardize a sodium hydroxide solution, which you do as you did in this lab. The average concentration is 0.1063M. He then hands you a solution of nitric acid and asks you to titrate it with your NaOH solution. It requires 27.33mL of your tandardized NaOH solution to titrate 24.79mL of the nitric acid solution. Write a chemical quation for the neutralization reaction and then calculate the molarity of the nitric...

A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 201.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 63.0mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide...

To standardize a solution of hydrochloric acid, you put 50.00 mL of it in a flask with a few drops of an indicator. You place 0.1524 M barium hydroxide in the buret. The buret reads 0.55 mL at the start and 33.87 mL when the equivalence point was reached. What is the molarity of the hydrochloric acid solution?
