What are the cations of group 1?

1. Group I Cations (Ag+, Hg22+ and Pb2+ – insoluble chlorides): Among the common metallic cations only three cations form insoluble chlorides with hydrochloric acid.

What is the other name of group 1 cations?

Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).

What is the color of the precipitate of group 1 cations?

2. A solution may contain one or more of the Group I cations. A white precipitate forms when 6 M HCl is added to the solution. The precipitate is insoluble in hot water.

Are group 1 cations soluble?

Generally, salts of the extremes on the periodic table (group 1 cations and group 17 anions) are soluble.

What is a cation and example?

Cations are positively charged ions. They are formed when a metal loses its electrons. They lose one or more than one electron and do not lose any protons. Therefore, they possess a net positive charge. Some examples of cations are Calcium (Ca2+), Potassium (K+), hydrogen (H+).

Why cations are classified into groups?

For the purpose of systematic qualitative analysis, cations are classified into various groups on the basis of their behavior against some reagents. The group reagents used for the classification of most common cations are hydrochloric acid, hydrogen sulphide, ammonium hydroxide, and ammonium carbonate.

Is group 1 cation or anion?

Certain groups of the periodic table form characteristic ions: Alkali metals (Group 1): +1 cations. Alkaline earth metals (Group 2): +2 cations.

Which cation is not present in group one?

First analytical group of cation contain of Ag+,Pb+2 and Hg22+. It does not consist of ferrous ion. Was this answer helpful?

What is a cation symbol?

The symbol for a cation is the element symbol or molecular formula, followed by a superscript of the charge. The number of the charge is given first, followed by a plus symbol. If the charge is one, the numeral is omitted.

How is a cation formed?

A cation has more protons than electrons, consequently giving it a net positive charge. For a cation to form, one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them.
