estion 22 ot yet swered When an acetic acid solution is titrated with sodium hydroxide, the slope of the titration curve (pH vs volume of NaOH added) increases when sodium hydroxide is first added. This change shows that arked out of 00 Select one: Flag question O a. the reaction is very slow during this part of the titration. O b. nothing is happening during this part of the titration. O c. a more concentrated solution of NaOH needs to be present to initiate the reaction. O d. the pH is not affected until all the acetic acid is consumed. O e. acetic acid is being converted to sodium acetate
