A 25mL portion of an unknown monoprotic acid solution was titrated with 1.5 M NaOH. It was found 20mL of this base was required to neutralize the sample. What's the molarity of the unknown acid solution?
A 0.040 M solution of a monoprotic acid is 14 percent ionized. Calculate the ionization constant of the acid.
A reaction is begun with a reaction mixture containing the following: [dye] = 1.0 x 10-4 M [bleach] = 0.10 M When [dye] = 8.0 x 10-5 M the rate is determined to be 3.74 x 10-7 M/min. When [dye] = 4.0 x 10-5 M the rate is determined to be 1.71 10-7..
