Experiment 16-Pre-Lab Assignment Name: 1. Design a preliminary procedure including sample calculations to determine the heat of neutralization for the reaction between 1.0 M HCl and 1.0 M NAOH in kJ/mol. Use your knowledge of the chemicals, their properties, and the laboratory techniques learned thus far in this course. Any chemicals and equipment that you require will be provided in the lab. This procedure must be approved by your instructor before you can begin experimentation. unpe 16-3

Q4. In this experiment, we add hydrochloric acid to our unknown sodium hydroxide solution during the titration. Sketch a sample pH curve showing how the pH of the titrated solution changes as we add more titrant. Be sure to label both axes of your graph and indicate the position of the equivalence point. C10 p Con Q5 You initially begin with a 0.1593 M hydrochloric acid solution. If you had a 125.0 mL sample of this hydrochloric acid solution, how many grams of HCl would be present in the sample? Show all work. Yourde tobl Q6 Write out a stepwise procedure (list of numbered steps) that you plan to execute when you come to lab to do the titration. (You instructor will review and offer feedback in person; you must have a written procedure before you can start the in-person portion of the final). You can assume you have access to the following equipment: buret/ring stand and buret clamp 25 mL graduated cylinder pipet pump 150 mL beaker (for waste) distilled water 50 mL buret 125 mL…
6. Open the bags and add 3 drops of bromothymol blue to each bottle. The indicator turns yellow if vinegar is still present and is blue-green when vinegar is not present. Record the color of each solution in the table provided. Data Table 1: Reaction Data Sample 7. Add a 4 teaspoon of baking soda to each bag. Effervescence of CO₂ occurs if excess vinegar is present. Record your observations in the table provided. Moles of vinegar (mol) Moles of baking soda (mol) mistry Relative size of bag Was excess vinegar present? Color with indicator?

Gravimetric analysis of chloride salts. What is gravimetric analysis? How is this theory applied in this experiment?
A good catalyst for a chemical reaction will ______________ Speed up the forward reaction and slow down the reverse reaction. Slow down the forward reaction and speed up the reverse reaction. Speed up both the forward reaction and the reverse reaction. Slow down both the forward reaction and the reverse reaction. Not affect either the speed of either the forward reaction or the reverse reaction.
d.The simplifying assumption that the change in concentration of the reactants is SMALL (and therefore negligible to the calculation) compared to the initial concentration of the reactants. Is this assumption justified in this reaction and these conditions? Do a little math to prove your point.
Part IV Cabbage Juice Indicator Chop cabbage into small pieces until you have about 2 cups of chopped cabbage. Boil for at least ten minutes to allow time for the color to leach out of the cabbage. Allow it to cool for 15 min • Filter out the plant material to obtain a red-purple-bluish colored liquid. 1. Add 1-2 drops of cabbage juice into a small bowl 2. Add 3-5 drops of vinegar into the bowl with the cabbage juice 3. Observe Is this a chemical change or physical change? Explain? Store the excess cabbage juice in your refrigerator, you will need them for future experiments.
