Question

Differentiate between the following with suitable examples- A basic radical and an acid radical

Distinguish Between

Solution

The positive part is called the basic radical and the negative part is called the acid radical.
A compound maybe consider having –

  1. A positive part [e.g. metal or ammonium ion]
  2. A negative part [e.g. chloride, bromide, sulphate, nitrate etc.]
Compound Positive part - Basic Radical Negative part - Acid radical
Sodium \[\ce{Na+}\] \[\ce{NO3-}\]
Ammonium \[\ce{NH4+}\] `"SO"_4^--`
Sulphate

\[\begin{bmatrix}
\ce{H}\\\ | \\\ce{N}\\\ / \phantom{...}|\phantom{..} \setminus\phantom{.}\\\
\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{H}
\end{bmatrix}^+\]

A liquid compound X of molecular mass 18 u can be obtained from a number of natural sources. All the animals and plants need liquid X for their survival. When an electric current is passed through 200 grams of pure liquid X under suitable conditions, then 178 grams of gas Y and 22 grams of gas Z are produced. Gas Y is produced at the positive electrode whereas gas Z is obtained at the negative electrode. Moreover, gas Y supports combustion whereas gas Z burns itself causing explosions.
