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.

The pHpH scale for acidity is defined by pH=−log10[H+]pH=−log10⁡[H+] where [H+][H+]is the concentration of hydrogen ions measured in moles per liter (M). A solution has a pHpH of 1.75. Calculate the concentration of hydrogen ions in moles per liter (M). What would the concentration be?
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.
(a) Calculate the percent ionization of a 0.20 M solution of monoprotic acetylsalicylic acid (aspirin) for which Ka = 3.0 x 10^-4. (b) The pH of gastric acid juice in the stomach of a certain individual is 1.00. After a few aspirin tablets have been swallowed, the concentration of acetylsalicylic acid in the stomach is 0.20 M. Calculate the percent ionization of the acid under these conditions.
pH is frequently used to define the acidity and alkalinity of an aqueous solution. It is defined by a mathematic equation as pH = -log10 [H+], where the H+ is the molar concentration of proton H+. pH can influence many chemical processes, such as complex formation, precipitation/dissolution, and reduction/oxidation reactions. Write down a relevant equation for each type of the mentioned chemical process and explain how pH can affect these processes. Do not write it on a paper and scan it.

Cranberry juice contains significant amounts of malic acid (H2C4H4O5), a diprotic acid, which accounts for its low pH. If one cup of cranberry juice contains 3.667 g of malic acid, calculate how many extra strength TUMS tablets would be needed to completely neutralize the malic acid (if extra-strength tablets contains 7.50 x 102 mg of CaCO3). Show your calculations in full.
The pH of a solution is a measure of its acidity or alkalinity. Specifically, pH = -log[H+] where [H+] is the hydrogen ion concentration in moles per liter. A solution with a pH less than 7 is an acid, one with a pH greater than 7 is a base (alkaline), and a pH of 7 is regarded as neutral.a)The hydrogen ion concentration of pure water is [H+] = 10-7 moles per liter. Find its pH.b) Find the pH of a solution with [H+] = 6.3 × 10-13 moles per liter.c) The pH of gastric acid (the acid in your stomach) is about 0.7. What is the corresponding hydrogen ion concentration?

The equilibrium constant for an acid is called the acid ionization constant (Ka). If acetic acid (weak acid, HC2H3O2) is placed into water, it ionizes to H+ and C2H3O2- with a Ka of 1.82 x 10-5. Determine the pH of the solution when 20.0 g HC2H3O2 (s) is added to water, with a final volume of 1000. mL?

(a) When Marco is sick, he tests the pH of his saliva and finds that it is 5.5. What is the hydrogen ion concentra- tion of his saliva? (b) Will the hydrogen ion concentration in Marco's saliva increase or decrease as he gets better? (c) After Marco recovers, he tests the pH of his saliva, and it is 6.5. Was the saliva more acidic or less acidic when he was sick?
