Q.22 write three solutions for the equation 7x-8y=13

How many times of the acetic acid concentration, acetate salt should be added to a given acetic acid solution to obtain a solution of pH = 7.0 ( K_a for CH_3COOH=1.8xx10^(-5) ) .

Calculate pH solution: 0.1 M CH_(3)COOH (K_a=1.8 xx 10^(-5))

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)

Cosider the equation int_(0)^(x) (t^(2)-8t+13)dt= x sin (a//x) If x takes the values for which the equation has a solution, then the number of values of a in [0, 100] is

Calculate pH solution: 10^(-8)M CH_(3)COOH (K_(a)=1.8 xx 10^(-5))
