Question

Positive ions from a base and negative ions from an acid form a .

Answer 1

Answer: Salt

Step-by-step explanation:

When an acid reacts with the base then it undergoes neutralization to form a salt and water.

Acids are those substances which dissociate in the water to give
`H^+` ions.

`HX\rightarrow H^++X^-`

Bases are those substances which dissociate in the water to give
`OH^-` ions.

`BOH\rightarrow B^++OH^-`

The reaction of neutralization can be represented as,

`H^++X^-+B^++OH^-\rightarrow B^+X^-+H_2O`

where
`BX` is the salt formed.

`H^++Cl^-+Na^++OH^-\rightarrow Na^+Cl^-+H_2O`

Answer 2

Positive ions from a base and negative ion from an acid form salt.

To add, table salt or common salt is a mineral composed primarily of sodium chloride, a chemical compound belonging to the larger class of salts. Rock salt or halite is also the common term for salt in its natural form.
