Astudent intends to titrate a solution of a weak monoprotic acid with a sodium hydroxide solution but reverses the two solutions and places the weak acid solution in the buret. after 23.75 ml of the weak acid solution has been added to 50.00 ml of the 0.100 m naoh solution, the ph of the resulting solution is 10.50. calculate the original concentration of the solution of weak acid.
