Find the concentration of h3o+ aq in a 1.75 m solution of lactic acid, hc3h5o2 at 25 c ka= 6.4x10^-5
Answers: 1
![Ka=\frac{[CH_3CH(OH)COO^{-}][H_3O^{+}]}{[CH_3CH(OH)COOH]}](/tpl/images/0139/6890/b7148.png)
![Ka=\frac{[CH_3CH(OH)COO^{-}][H_3O^{+}]}{[CH_3CH(OH)COOH]} \\ \\ Ka=\frac{[x][x]}{[1,75M-x]} ---(1,75M-x\approx 1,75M) \\ \\ \sqrt{6,4*10^{-5}*(1,75M)}=x=0,0106M=[ H_3O^{+}]](/tpl/images/0139/6890/2521d.png)
