Combining capacity of sodium

Explanation:

The combining capacity of an atom is its ability to make bonds with other elements. It is also known as valency or valence. The number of valence electrons of an atom gives us an idea of the combining capacity. Some atoms like to donate or gain electrons, while others share them to combine with another atom.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
