Concept explainers
(a)
Interpretation:
Three common weak acids are to be named.
Concept introduction:
Acid is a substance that dissociates in water to release H+ ions. Depending upon the strength the acids can be classified into two types:
1. Strong acids
2. Weak acids
Strong acids are the substance that dissociates completely into its ions when dissolved in the solution. They dissociate completely in water to release H+ ions. They behave as strong electrolytes and conduct a large amount of electricity.
Weak acids are the substance that does not dissociates completely into its ions when dissolved in the solution. They dissociate partially in water to release H+ ions. They behave as weak electrolytes and conduct less amount of electricity.
(b)
Interpretation:
One common weak base is to be named.
Concept introduction:
A base is a substance that dissociates in water to release OH− ions. Depending upon the strength, bases can be classified into two types:
1. Strong bases
2. Weak bases
Strong bases are the substance that dissociates completely into its ions when dissolved in the solution. They dissociate completely in water to release OH− ions. They behave as strong electrolytes and conduct a large amount of electricity.
Weak bases are the substance that does not dissociates completely into its ions when dissolved in the solution. They dissociate partially in water to release OH− ions. They behave as weak electrolytes and conduct less amount of electricity.
(c)
Interpretation:
The major difference between a weak acid and a strong acid or between a weak base and a strong base and the experiment to observe it is to be determined.
Concept introduction:
Acid is a substance that dissociates in water to release H+ ions. The dissociation reaction of acid is:
HXH2O→H+(aq)+X−(aq)
A base is a substance that dissociates in water to release OH− ions. The dissociation reaction of the base is:
MOHH2O→M+(aq)+OH−(aq)
Depending upon the strength of dissociation, acids, and bases can be classified into two types:
1 Strong acids and strong bases
2. Weak acids and weak bases

For each reaction in the assignment, you must write each mechanism three times (there are 10 reactions, so 30 mechanisms). (A) do the work on a tablet and save as a pdf., it is expected to write each mechanism out and NOT copy and paste the mechanism after writing it just once. Everything should be drawn out stepwise and every bond that is formed and broken in the process of the reaction, and is expected to see all relevant lone pair electrons and curved arrows.arrow_forwardNonearrow_forward
