Solution A has a a hydronium ion concentration of 1.3 x 10^-3 M. Solution B has a hydroxide ion concentration of 4.5 x 10^-8M. Calculate the pH of solutions A and B Show all calculations?

##pH_A## ##=## ##2.89##
##pH_B## ##=## ##7.44##
By definition, ##pH## ##=## ##-log_10[H_3O^+]##.
##pH_A## ##=## ##-log_10[1.3xx10^-3]=2.89##
##pOH_B## ##=## ##-log_10[4.5xx10^-8]=7.44##
Since ##pH+pOH=14##, ##pH_B## ##=## ##6.56##
What does it mean when we say ##log_AB=c?##
Can you tell me the values of ##log_(10)10## and ##log_(10)100?##
