A titration of Solution A had already begun when Brian began taking measurements of the concentration values in moles. Solution B was being used as a control and
was not being titrated. The concentration of Solution A was increasing and represented by A(x) = 2log(2) + log(x + 1), where x represents time in hours since the
beginning of the titration. The concentration of Solution B was constant and represented by B(x) = log(16).
a. How long after Brian began taking concentration measurements was the concentration of Solution A equal to the concentration of Solution B? What was the
concentration amount? Solve the problem algebraically.
b. How long was this from the beginning of the experiment?
c. Justify the reasonableness of your response.
