I need answers of a Chemistry Lab Between acids and bases reaction?

Question

Well the experiment was the following measure 2 ml of HCl and add 2 drops of phenolphthalein and start adding drops of NaOH until the solution become from colorless to pink the same steps were with 4ml of HCl and with 2 ml of H2SO4

the results where the following

TABLE 1
HCl (volume) NaOH ( drops )
2ml 61
4ml 98

TABLE 2
H2SO4 (volume) NaOH ( Drops )
2ml 101

and the questions are:

1) analyzing results compare your responses to analysis item 1. Is there a difference in the average number of drops? What is the ratio between these two numbers? Is it 1:1, 1:2, 2:1, or 1:3? Explain the "chemistry" behind this ratio.

2)1. Now compare your responeses to analysis items 1 and 2. (the same from above)...Is it 1:1, 1:2, 1:3, etc?...(the same from above)

3)Based on your observed results, how many drops of NaOH would be neede to react completely with a 2ml sample of HNO3?

HNO3 + NaOH -> NaNO3 + H2O

Answer 1

1) 1:1

2) 1:1

3) Same

Answer 2

Katie's answer is astonishing, different than that some experiments start up with an theory or theory, particularly than a hypothesis; it somewhat is somewhat the top from working a prior set of experiments, a reasoning and is the reason the outcomes (it does not could desire to be properly suited!). you are able to desire to incorporate a precis or precis that is going on the front of the artwork, 3 paragraphs that tells of your suggestions, what you discovered, and your conclusions. Jimmy is robust relating to the protection factors, do a risk assessment, its not confusing, artwork out what the negative aspects are (the flaws that have intrinsic possibility, like some chemical compounds), and wager what the possibility of injury is possibly to be, and teach the way you mitigate against it.
