Why Fecl2 and Sncl2 Exist Together?

The compounds with lower oxidation number

oxidation number
The increase in the oxidation state of an atom, through a chemical reaction, is known as oxidation; a decrease in oxidation state is known as a reduction. Such reactions involve the formal transfer of electrons: a net gain in electrons being a reduction, and a net loss of electrons being oxidation.

and which cannot reduce by one another can exist together. ... The compounds with lower oxidation number and which cannot reduce by one another can exist together. Thus, FeCl2 and SnCl2 can exist together as Fe2+ can not be reduced by Sn2+.

What is are the pairs that Cannot exist together in a mixture Why can't those pairs exist?

NaHCO3 is a sodium salt of weak acid, while NaOH is a strong base, that is why they react and cannot exist together in solution.

Which of the following can not exist together in aqueous solution?

Solution: Sodium bicarbonate and sodium hydroxide cannot exist together in the aqueous solution because they react with each other. Sodium bicarbonate acts like an acid and sodium hydroxide acts as a base. The products of the reaction are sodium carbonate and water.
