Assume 100 percent rejection of all solutes and & polarization factor of 1.15 and ignore activity coeficients (i.e., activity = concentration). Desired [OH-] = ? Assume a volume of 15.0 L. Calculate the freezing point and normal boiling points of each of the following aqueous solutions. 2. See the discussion of this reaction in the section on the Haber process.

WebBorax dissolved in water equation Hint: Borax reacts to give an alkaline solution. when methanol, ch3oh, is dissolve in water, a nonconducting solution reslults. What is the pH of a 0.02 M solution of the strong base KOH? When an ionic compound dissolves in water, it dissociates into its ions. Solution This problem requires the application of Henrys law. A vinegar solution has [H3O+] = 2.0 x 10-3. a) What is the hydroxide ion concentration in the vinegar solution? The exothermic reaction gives off a lot of heat, and can actually boil the water it is dissolved in. 6.0 Methanol is a simplest alcohol with a chemical formula CH3OH.

NH_4OH(aq) -> NH_4^+(aq) + OH^(-)(aq) When ammonium hydroxide is dissolved in water, the ion-water attraction overcomes the attraction between ions, so it dissociates into the ammonium cation and hydroxide anion. The Hydrochloric acid dissolves as ions which conduct electricity being charged particles. But I just wanted to say that if there is even a slight difference in their solubility( say at the 10th decimal place {solubility in mol/litre}), then its probable reason is the one I gave.
