Fe3+(aq) (yellow) + scn-(aq) (colorless) fescn2+(aq) (blood-red) chloride ions are colorless. potassium ions are also colorless. the above equilibrium can be created by mixing an iron (iii) chloride solution with a potassium thiocyanate solution. based on this information and the colors in the equilibrium above answer the first two questions. 1. what color would an fecl3 solution be? 2. what color would a kscn solution be? 3. what color do you get when you mix fecl3 and kscn as shown in the video for the control test tube?

Explanation:

The above two reactions xcan also be written in form of single chemcial equation:

1. Color of ferric chloride solution is yellow. This is due to presence of ferric ions which have yellow color in their aqueous solutions.

2. KSCN has the colorless solution. This due to potassium ion forms colorless aqueous solution.

3. On mixing, KSCN with we will get blood red color solution of .

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
