A 15% alcohol solution means

Calculate the pH at the equivalence point when a solution of 0.1 M CH_3COOH is titrated with a solution of 0.1 M NaOH. K_a(CH_3COOH)= 1.8 xx 10^(-5)

A solution is 0.09 M in HCl and 0.09 M in CH_(2)ClCOOH . The pH of the solution is 1 . What is the K_(a) for CH_(2)ClCOOH ?

Aqueous solution of HNO_(3),CH_(3),CH_(3)COOH , and CH_(3)COOK of identical concentrations are given. The pair (s) of the solution which may form a buffer upon mixing is (are):

Which of the following solutions when added to 1L of a 0.1 M CH_3COOH or in the pH of the solution K_a=1.8xx10^(-5) for CH_3COOH ?

a. Write an equilibriu equation for a solution containing CH_(3)COOH and CH_(3)COONa . What effect does CH_(3)COONa have on a solution of CH_(3)COOH ? b. What reagents should be added to a solution to increase i. [CH_(3)COO^(Theta)] ii. [overset(o+)NH_(4)]

If it is given that x=9 is a solution of the equation ln(x^(2)+15a^(2))-ln(a-2)=ln((8ax)/(a-2)) then
