Question

I just did an experiment and I'm so lost as to how to complete the questions...

Answer 1

1. Write the balanced equation for the reaction of acetic acid ( ) and sodium bicarbonate ( ). What type of reaction(s) took place?

2. Calculate the number of moles of that were required to neutralize the in the vinegar.

3. Calculate the molarity of the vinegar sample. (Don’t forget to convert mL to L.)

4. Calculate the number of grams of in the vinegar.

5. Calculate the percent of acetic acid in the vinegar. (The density of vinegar is 1.002 g/ml.)

6. Is it possible for the equivalence point of a titration to not be at pH 7? Explain your answer.

7. What is the molarity of a CsOH solution if 30.0 mL of the solution is neutralized by 26.4 mL 0.25 M HBr solution?

Answer 2

how do u think u should go about this question

Answer 4

this might help

Answer 5

Well for the table I think I should take 18.66 and divide that by the drops I put in my solution, but it doesnt make sense when I calculate them back out. I got 18.66 by dividing 92 (how many drops it takes for my dropper to get to 1 tsp) by 4.93 (1 tsp = 4.93 mL).

Answer 6

And I need to convert my drops to mL. But When I calculate it out it's like 1.339.... so that doesn't really make sense. Hang on while I look at that website.

Answer 7

I think one drop is 0.5 ml but I'm not sure

Answer 8

it depends on the apparatus used

Answer 9

what apparatus did u use for the drops

Answer 10

Right I think it is normally but it had me like "calibrate my eyedropper" and then thats what I got

Answer 11

you got one drop to equal 0.5 ml?

Answer 12

No One drop was 18.66 mL

Answer 13

I dont know I think that sounds wrong now that I think of it....

Answer 14

It said to use an eyedropper but I got a medicine dropper. I couldn't find an eyedropper.

Answer 15

ok I never used a medicine dropper before so I cant really say but this may sound like plenty work but I think its best retest for volume one drop holds to move on

Answer 16

Oh okay. I mean whatever is going to get me the right results!

Answer 17

yes true I hope you get through

Answer 18

Thanks mee too :)

Answer 19
