Q5. Why are some salts acidic when others are neutral?

1 answer:

6 0

The pH will remain neutral at 7. Halides and alkaline metals dissociate and do not affect the H+ as the cation does not alter the H+ and the anion does not attract the H+ from water. This is why NaCl is a neutral salt.

Predict the chemical formula of the compound that will form when Li and o interact.

Ksivusya [100]

Answer:

$Li_2O$

Explanation:

Hello!

In this case, when looking over the chemical formula of a compound formed when two elements interact, we need to realize about their location in the periodic table; thus, since lithium is a metal and oxygen a nonmetal, we infer lithium turns out the cation and oxygen the anion. Moreover, as the oxidation state of lithium is 1+ and that of oxygen is 2-, we can set up the chemical formula as follows:

$Li^+O^{2-}\\\\Li_2O$
