When sodium acetate dissolves in water the resulting pH is above 7. This is because Sodium ion reacts with water to produce hydroxide ions. O Sodium ion is the cation of a strong base and acetate is the anion of a weak acid. Acetate ion reacts with hydroxide ions to produce excess protons. none of these answers Knowing the pH of a solution will allow one to know the pOH as well. O True...

Describe the process that takes place between the participants in the neutralization reaction between the strong acid nitric acid, HNO3(aq), and the strong base potassium hydroxide, KOH(aq), forming water and potassium nitrate, KNO3(aq). Mention the nature of the particles in the solution before and after the reaction. (a) Because nitric acid is ---Select--- an acid a base a binary covalent compound a binary ionic compound an oxyacid , it reacts with water to form ---Select--- hydrogen atoms hydronium ions hydroxide ions protons...

4) Why is the pH of a 0.1 M solution of sodium fluoride not equal to 7? A) The sodium ion reacts with water to release hydroxide ions, making the solution basic. B) The floride ion reacts with water to release hydroxide ions, making the solution basic. The sodium ion reacts with water to release hydrogen ions, making the solution acidic. D) The fluoride ion reacts with water to release hydrogen ions, making the solution acidic.

Polyprotic acids have more than one proton to donate to water, therefore have more than one equilibrium constant for proton donation. For phosphoric acid, there is a three-step equilibrium: H, PO +H,0 5 H2PO4 + H30* H,PO," +H,0 5 HPO - +H30* HPO 2- +,0 5 PO.- +,0* Kai = 7.11 x 10-3 Ka2 = 6.32 x 10-8 Ka; = 4.5 x 10-13 For all conjugate acid base pairs: K, XKK where K is for the reaction...

14. (3 pts.) The ionized benzoic acid dissolves better in water than it does in diethyl ether, which is how and why it is extracted into the water phase. Give the most important IMFs that are responsible for solubilizing the benzoic acid anion in the water. Give also the most important IMFs that are responsible for solubilizing the sodium cation in the water. The kinds of strong IMF that could be present are ion-dipole, hydrogen bonding (ignore dipole-dipole and induced...
