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:.

h let me think

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
