Calculate the ph of a 0.25M solution of monochloroacetic acid at 25 c

Chemistry
1 answer:
Phoenix [80]2 years ago
8 0
<h3>Answer: <em>pH=2.25 </em></h3>

Explanation:

monochloroacetic acid  also means: chloroacetic acid

pKa of monochloroacetic acid= 1.4 x 10^-3  (I believe this should have been given in the problem or perhaps in the textbook)

Formula: pH= pKa + log ( some number in M)

pH= -log (1.4 x 10^-3) + log (0.25M)= 2.85 + -0.602= 2.25

pH= 2.25

Answer:

6.50 g of Hydrogen

Explanation:

We know that in every 20.0g of sucrose, there are 1.30g of hydrogen.

We now have 100.0g of sucrose. 100.0g is 5x larger than the 20.0g sample, which is a 5 : 1 ratio. Applying this ratio to the amount of hydrogen, we would have 5*1.3g of hydrogen in the 100.0g of sucrose.

5*1.3 = 6.5, so our answer is that there are 6.50g of hydrogen in 100.0g of sucrose.

Hope this helps!
