How do you find Keq if given an equation and Ka and Kb? EX: Someone found a smashed box of smelling salts in a storage closet of Fauver Stadium. The field hockey team manager, being a chemistry pro, knew that if she could convert all of the ammonia (NH3) found in the smelling salts into an ammonium salt (NH4+ + X), she could get rid of the horrid smell. If the closet contained 100 mL of 1.0 M NH3 solution and the field hockey team manager/chemistry pro added 100 mL of a 1.0 M solution of H2SO4. Kb for NH3 = 1.73 • 10-6, Ka for H2SO4 = 1000, Ka for HSO4-= 1.2 • 10-2 a. Provide a keq value for each of the following... H2SO4 + NH3 =HSO4 + NH4 HSO4 + NH3=SO4+ NH4 NH3 + H20= OH- + NH4 NH4 + H20= NH3 + H30 SO4 + H20= HSO4 + OH-

Ionic Equilibrium

Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.

Arrhenius Acid

Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.

Bronsted Lowry Base In Inorganic Chemistry

Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.

Question

How do you find Keq if given an equation and Ka and Kb?

EX: Someone found a smashed box of smelling salts in a storage closet of Fauver Stadium. The field hockey team manager, being a chemistry pro, knew that if she could convert all of the ammonia (NH3) found in the smelling salts into an ammonium salt (NH4+ + X), she could get rid of the horrid smell. If the closet contained 100 mL of 1.0 M NH3 solution and the field hockey team manager/chemistry pro added 100 mL of a 1.0 M solution of H2SO4.

Kb for NH3 = 1.73 • 10-6, Ka for H2SO4 = 1000, Ka for HSO4-= 1.2 • 10-2

a. Provide a keq value for each of the following...

H2SO4 + NH3 =HSO4 + NH4

HSO4 + NH3=SO4+ NH4

NH3 + H20= OH- + NH4

NH4 + H20= NH3 + H30

SO4 + H20= HSO4 + OH-

Hydroiodic acid often is used to disinfect and sanitize medical tools and products. In an experiment, 5.0 mL of 0.75 mol/L HI(aq) is mixed with 20.0 mL of distilled water. (record only your final answer with the correct number of significant digits and the proper units.) 1. What is the hydronium ion concentration of the resulting diluted solution? 2. What is the pH of the resulting solution? 3. If 1.0 mL of the diluted solution is added to 9.0 mL of distilled water, what is the resulting pH of the solution? 4. If 1.0 mL of the diluted solution from #3 is added to 9.0 mL of distilled water, you should be able to predict the pH based on the trend you see and without doing any calculations. This is because every time the hydronium concentration a) increases b)decreases by a factor of 10, the pH goes up one full unit since the solution becomes a)more b)less acidic.
A student is given a 2.002 g sample of unknown acid and is told that it might be butanoic acid, a monoprotic acid (HC4H7O2, equation 1), L-tartaric acid, a diprotic acid (H2C4H4O6, equation 2), or ascorbic acid, a diprotic acid (H2C6H6O6, equation 3). If it requires 39.55 mL of 0.570 M NaOH(aq) to neutralize the unknown acid, what is the identity of the unknown acid? Justify your answer. HC4H7O2(aq) + NaOH(aq) → NaC4H7O2(aq) + H2O(l) (1) H2C4H4O6(aq) + 2NaOH(aq) → Na2C4H4O6(aq) + 2H2O(l) (2) H2C6H6O6(aq) + 2NaOH(aq) → Na2C6H6O6(aq) + 2H2O(l) (3) butanoic acid E. butanoic or ascorbic acid B.

What would be the hydronium ion concentration in a solution 0.100 M NaOH and 1.00 M NH3? (Hint: NaOH and NH3 are both bases. So there are two sources of hydroxide ions. NaOH is a strong base, but NH3 is weak so you will have to use Kb. Add them together, then plug the sum into the Kw equation to find hydronium, then find pH.)

Sulfuric acid is acidic, but what would be the pH, the sulfuric acid concentration [H2SO4]eq, hydrogen sulfate ion concentration [HSO4-]eq, and sulfate ion concentration [SO42-]eq be for a sulfuric acid solution made in the lab by diluting 13.3 mL of 3.0 M stock sulfuric acid to a total volume of 500 mL. Ka1 = Large and Ka2 = 0.011.
The acidity or alkalinity of a solution is defined by pH = –log[H+] where [H+] is the hydrogen ion concentration, measured in moles per liter. Solutions with a pH value of less than 7 are acidic; solutions with a pH value of greater than 7 are basic and solutions with a pH of 7 (such as pure water) are neutral. Suppose that you test apple juice and find that the hydrogen ion concentration is [H+] = 0.0003. Find the pH value and determine whether the juice is basic or acidic. You test some ammonia and determine the hydrogen ion concentration to be [H+] = 1.3 × 10– 9. Find the pH value and determine whether the ammonia is basic or acidic.
