Similar to mole-based concentration units in for solutions, such as molarity and molality, osmotic systems have their own version of these concentration units called osmolarity and osmolality.

Now we have something straight from the Arrhenius-Ostwald model. The second ionization (Eq. 7) is the more important one at pH 9. The monohydrogen tetraborate ion has a pKa of 9; hence, in our buffer system we would expect about equal amounts of HB 4 O 7-and B 4 O 7 2-.The species "H 2 B 4 O 7", having a pKa of about 5 (Latimer and Hildebrand, 1940), would not be present in significant amounts.

acid is fully ionized. From the equation, the molar concentration of OH − is 10 −13.For a 0.1 M solution of NaOH, the OH − is 0.1 M , but the hydrogen ion concentration is 10 −13.Hence, the value of the exponent for hydronium ion concentration goes from −1 in strong 0.1 M acid to −13 in strong 0.1 M base.

In agreement with the intensity trend in the vibrational bands, also the polaronic transition of PCPDT appears at lower molar concentration with respect to what we observe in the copolymer.

Concentration of a solution expressed in gram percentage, is simply the mass in grams of the solute per 100 ml of solution. So if we convert our known value of 180 milli molar to molarity we just move.

Chemistry isn’t just about memorizing chemical formulas or calculating molar masses. Well. The multiple simultaneous reactions cause the concentration of iodine to rock back and forth and change.
