In the laboratory, you have a beaker containing 100 milliliters (ml) of naoh solution at ph = 13. into this beaker, you carefully pour 10 ml of hci at ph = 1. which of the following statements best describes how the original contents of the beaker will be changed by this mixing?
a. at 25 °c, the product of [ht] and [oh] will be 10 -12 after mixing.
b. the concentrations of h+ and oh- ions will become equal.
c. the ph of the beaker's contents will increase.
d. the ph of the beaker's contents will decrease. o e. the concentration of na+ ions will increase.
