explain the following terms & give their examples :
(a) Strong acid (b) Weak acid
(c) Strong base (d) Weak base
Answers
Answer:
Explanation:
Ans:a)Strong acids completely dissociate into ions in solution. For example, hydrochloric acid is a strong acid. It ionises completely to form hydrogen ions and chloride ions: HCl(aq) → H +(aq) + Cl -(aq) Nitric acid and sulfuric acid are also strong acids.
Ans:b)Weak Acids are the acids that do not completely dissociate into their constituent ions when dissolved in solutions. When dissolved in water, an equilibrium is established between the concentration of the weak acid and its constituent ions. Some common examples of weak acids are listed below.
Ans:c)A strong base is something like sodium hydroxide or potassium hydroxide which is fully ionic. You can think of the compound as being 100% split up into metal ions and hydroxide ions in solution. ... Some strong bases like calcium hydroxide aren't very soluble in water.
Ans:d)A weak base is a chemical base that does not ionize fully in an aqueous solution. As Brønsted-Lowry bases are proton acceptors, a weak base may also be defined as a chemical base with incomplete protonation.
Answer:
A-An acid that breaks down completely and gives off many ions, or protons, is considered to be a strong acid. Examples of strong acids include sulfuric acid, hydrochloric acid, perchloric acid, and nitric acid
B-A weak acid is one that does not dissociate completely in solution; this means that a weak acid does not donate all of its hydrogen ions (H+) in a solution. ... Examples of weak acids include acetic acid (CH3COOH), which is found in vinegar, and oxalic acid (H2C2O4), which is found in some vegetables.
C- A strong base is a base that is completely dissociated in an aqueous solution. These compounds ionize in water to yield one or more hydroxide ion (OH-) per molecule of base. ... Ammonia is a good example of a weak base. Strong bases react with strong acids to form stable compounds.04-Nov-2019
D-Weak bases are the basic substances that do not completely ionize in water. An example of a weak base is ammonia. When NH3 is dissolved in water, a part of it dissociates into ammonium cation and hydroxide anions by interacting with the water molecules.
