Question

7. A variety of different types and brands of commercial vinegars will be available for you to investigate the acid content in this experiment. Assume you will study three different vinegars. Give something (a question) that you might seek to answer from your data collection.

Answer 1

1.A compound is acidic in solution if it strongly dissociates to give H⁺ ions in the solution.

2.more are the number of H⁺ ions more is the acidic strenth.

3.vinegar contains acetic acid ( CH3COOH ) which gives it acidic strength.it is a weak acid that is it is already less dissociated.but concentration can give us some idea about the acidic strength

4.more is the concentration more are the chances of dissociation hence more will be the acidic strength.

5.strength of vinegar can be described by its CONCENTRATION (amount of acidity in a given volume of liquid and which is measured in percent) or Its ACIDITY, which is measured as a pH value.

6.To measure the pH of vinegar use a pH strip. Resulting color will tell you how strong the Vinegar is. Distilled white vinegar usually measures around pH 2.4 with a strength of 5%. The lower the pH, the more acidic the vinegar is.that is more no of H⁺ ions lower is the pH value.

7.thus one question may arise about the acidic strength of different samples of vinegar. thus you may answer the question about acidic strength from your data collection by measuring pH values.
