What are basic radicals?
-Basic radical is also an ion which is basic in nature and is coming from a base. It is a positively charged chemical species. We can also call it cation. It can be a portion of an inorganic salt. By removing the hydroxyl ion from a base, we can get a basic radical.
What are radicals acidic?
Acid radical is the ion formed after the removal of Hydrogen ion (H+) from an acid. Example: When H2SO4 loses H+ ion, it forms HSO4− which is an acid radical. The ion formed after the removal of hydroxide ion (OH−) from a base is known as basic radical.
What are acidic radicals examples?
Acidic radical are anions which are negatively charged. For example: SO42-, NO3¯, etc. Basic Radicals are cations which are positively charged. For example: Na+, Fe++, etc.
What is acid and basic radicals in salt analysis?
Salt Analysis Answer Format (Sample) Aim: To identify the acidic radical and the basic radical of the given inorganic salt. Result: The acidic radical is (anion), and the basic radical is (cation). Therefore, the given salt is identified to be (salt).
Why are cations called basic radicals?
Cation and anion are called basic and acidic radicals, respectively, because during salt formation cation comes from base and anion comes from acid. Metal ions or cations are basic radical reactions with acidic radicals. This results in the formation of salt. Most of the metal- Ferrocyanide complexes are coloured.
How many basic radicals are there?
. The radicals are of two types – acidic radicals and basic radicals.
Are cations acidic or basic?
Note that all cations, except those of alkali and alkaline earth metals ( which do not hydrolyze in water and, therefore, do not affect pH ), act as weak acids in solution.
Is nitrate a basic radical?
In sodium nitrate Na+ is basic radical and NO-3 is acidic radical.
How many groups are there in basic radical?

What is cation and anion?
Cations are positively-charged ions (atoms or groups of atoms that have more protons than electrons due to having lost one or more electrons). Anions are negatively-charged ions (meaning they have more electrons than protons due to having gained one or more electrons).
Are anions bases?
In basic salts, the anion is the conjugate base of a weak acid. In general, anions A- can be considered the conjugate base of the acid HA. Depending on the strength of the corresponding acid: • A-, the conjugate base of a weak acid, acts as a weak base. A-, the conjugate base of a strong acid, acts as a pH-neutral.
