Write out what data and information you plan to collect during the experiment of identification of a weak diprotic acid using titration to answer how can a weak diprotic acid be identified when titrated with a strong base?Then list the equations and formulas you plan to use to manipulate that data.Also list how many trials you plan to do? If it's just one or more?

List all the chemicals you are going to use or encounter from the experiment of identification of a Weak Diprotic Acid using Titration?  What materials that have specific hazards or safety concerns? Then list out the glassware, tools, equipment and other materials you think you are going to need for the experiment of Identification of a Weak Diprotic Acid using Titration?

Can you confidently dtermine if the molarities are precise? Explain why or why not.

1. Write a chemical equation that will explain why an acid is produced when carbon dioxide is dissolved in water. 2. If Phenolphthalein was added to a flask that contained everything that is described in question 1, what color would the solution be? 3. If a universal indicator was added to a flask that contained everything that is described in question 1, what color would the solution be? 4. What are buffers good at doing?

Can you confidently determine if the molarities are accurate? Explain why or why not.

a. You are collecting waste at your lab bench throughout the experiment and you need to put it somewhere. What glassware piece would you use for the waste?b. While doing an experiment you need to test pH of a solution. Only a milliliter or two of solution is required for this test. Which piece of glassware will you put them in?c. A reaction requires that you mix two solutions (50 mL each) and then heat gently for 30 minutes. Whichpiece of glassware would you use to conduct this reaction?d. A reaction requires 11.50 mL of solution. Which piece of glassware would you use to measure the right volume?e. There’s a big container of stock solution that will be used by the entire class. However, each reaction requires only approximately 20 mL of solution. What container would you use to carry 20 mL of solution to your lab bench, before measuring it accurately?

QUESTION 4 Standardizing a solution of sodium hydroxide for our acid-base titration experiment means O a. to prepare a series of standard solutions and determine the average concentration. O b.to prepare the standard solution directly from a solid and not from a solution. O c. to compare the results of your titration with those of other laboratories, or other groups performing the same titration. O d. to determine, by titration , the concentration of the basic solution using a known quantity of a primary standard acid. Click Save and Submit to save and submit.

Part C – Acid–base and solubility equilibria 1. Rinse 4 regular size test tubes and a 10 mL measuring cylinder thoroughly with water. Number the test-tubes from 1 to 4 in a test tube rack. 2. Into each of test tubes 1 – 3 put a small amount of solid benzoic acid (put the same amount – about the size of a pea – in each test tube). 3. Add 2 mL (use the measuring cylinder) of water to tube 1 and shake to mix the contents. 4. Add 2 mL (measuring cylinder) of 2 M HNO3 to tube 2 and shake to mix the contents. 5. Rinse the measuring cylinder with water, then use it to add 2 mL of 2 M NaOH to tube 3 and shake for about 10 seconds to mix the contents. Rinse the measuring cylinder. 6. Pour about half of the solution from tube 3 into tube 4, than add 2 mL of 2 M HNO3 to tube 4. 7. Allow the test tubes to stand for 2 or 3 minutes then record the appearance of the mixtures in each test tube. 8. Answer the questions on the results page relating to this equilibrium system.
