Consider how best to prepare one liter of a buffer solution with pH = 3.79 using one of the weak acid/conjugate base systems shown here. Weak Acid Conjugate Base Ka pKa HC2O4- C2O42- 6.4 x 10-5 4.19 H2PO4- HPO42- 6.2 x 10-8 7.21 HCO3- CO32- 4.8 x 10-11 10.32 How many grams of the sodium salt of the weak acid must be combined with how many grams of the sodium salt of its conjugate base, to produce 1.00 L of a buffer that is 1.00 M in the weak base? grams sodium salt of weak acid = grams sodium salt of conjugate base =
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.
Consider how best to prepare one liter of a buffer solution with pH = 3.79 using one of the weak acid/conjugate base systems shown here.
| Weak Acid | Conjugate Base | Ka | pKa |
|---|---|---|---|
| HC2O4- | C2O42- | 6.4 x 10-5 | 4.19 |
| H2PO4- | HPO42- | 6.2 x 10-8 | 7.21 |
| HCO3- | CO32- | 4.8 x 10-11 | 10.32 |
