Aspirin (acetylsalicylic acid, c9h8o4) is a weak monoprotic acid. to determine its acid-dissociation constant, a student dissolved 2.00 g of aspirin in 0.600 l of water and measured the ph. what was the ka value calculated by the student if the ph of the solution was 2.60?

The value of the dissociation constant will be:.

Explanation:

At ,t= 0      c              0     0

At eq'm   (c-x)            x     x

Concentration of aspirin = c

Expression for dissociation constant will be given as:

..(1)

The pH of the solution  = 2.60

The pH of the solution is due to free hydrogen ions whcih come into solution after partial dissociation of aspirin.

Putting value of x in (1).

The value of the dissociation constant will be:.

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

explanation:

the answer is minerals.
