Ionization constant of weak acid is 10 -4

WebAlthough the ionization constants for all weak acids are relatively small (otherwise the acid would not be a weak acid), they do vary in magnitude. The smaller the constant, the less the acid ionizes, and the weaker the acid. Table 15.5 lists the acid ionization constants for a num-ber of common weak acids in order of decreasing acid strength. WebBut we are asked to find the percent ionization which will be equal to my either either concentration divided by my initial concentration and of course times 100 to turn into a percent. So that will be 3.35 times 10 to the minus fourth bowler, divided by 0.75 bowler times 100. And the two significant figures. I got 4.5%.
