I'm not the original poster but still interested in solving this problem. Following your hint, the following is the expression I ended up with. A_n = A_(n-1) * (n+1) + 2(n+1) How do I go about resolving A_(n-1) to a function/expression in terms of n?

I got it, thanks a lot! Also sorry for not reading the posting guidelines beforehand.

this is the given problem: and this is my attempt at a solution: I am stuck here as the variable y is unknown and I want to express y in terms of x, but cannot figure out how to do so. Thanks for any help!

ah ok sorry

how would i go about solving for the pH then?

so is my pH value correct ?

Malonic acid can ionise in two stages as it is a dibasic acid. The values of pKa1 and pKa2 of malonic acid are 2.85 and 5.70 respectively. Calculate the pH of the first and second equivalence points of the titration of 10cm^3 of malonic acid of concentration 0.1 M with sodium hydroxide of...
