How might cations in group 1 be separated from cations in group 2?

If your Group 2 cations are calcium, strontium or barium, add a solution containing sulphate ions, i.e. sulphuric acid or the sulphate of the Group I metal that is the Group I cations in your solution. The Group 2 cations will precipitate out with the sulphate ions. If you have beryllium or magnesium cations, then I don't know.

What is the group precipitant of group 1 cations?
HCL
Where is cation on the periodic table?
Periodic table consists of elements not cations. However group 1 and group 2 elements (left side of the periodic table) are elements which will form cations easily.
How do elements in group 1 react with elements in group 15?
Elements in group 15 (or group 5) are non-metals. Thus, elements in group 1 lose electrons, forming positively charged cations, which are gained by elements in group 5, forming negatively charged anions. The attraction between anions and cations is known as an ionic bond. Example, the reaction between sodium and nitrogen: 2 Na(s) + 3 N2(g) --> 2 Na3N(s) The formula is due to sodium having a valency of 1 and nitrogen having a valency of 3. These 'cross over' producing the symbolic formula Na3N.
What group in the periodic table will form cations?
Metals form cations (positive ions).
How reactive are lanthanides and actinides metals?
lanthanides and actinides are fairly reactive, but not as much as say, the alkali metals in group 1
What is the group precipitant of group 1 cations?
HCL
Why are the group 1 cations removed as insoluble chlorides?
because it does
Why are elements in group one of the periodic table cations?
The elements of group 1 has 1 valence electron. They lose 1 electron to form cation.
Which group in the periodic table will form cations with a 3 positive charge?
a group that forms anions with a -1 charge
What is the ratio of anion to cations in a compound formed by a group 2A metal and a group 7A nonmetal?
1 to 2
Is group 7A cations?
Halogens (group 7A) form ions with a 1- charge.
What group of elements forms 1 cations?
Alkali metals, Li Na K etc
Elements in group 1 of the periodic table lose one electron to form ions with what?
These cations have the electrical charge +1.
Do element in the s block have more than one charge?
Usually these elements have a single valency. Those in group 1 form singly charged cations while those in group 2 form doubly charged cations.
What group of elements forms 1 plus cations?
Alkali metals, Li Na K etc
How are Group one of the periodic table different from any other?
Group-1 are alkali metals. They are highly metallic. Their valence electron is 1. They loose 1 electron to form cations.
Where is cation on the periodic table?
Periodic table consists of elements not cations. However group 1 and group 2 elements (left side of the periodic table) are elements which will form cations easily.
