What is the net ionic equation of CuBr2+Na2S=CuS+2NaBr?

.

Explanation:

Start by identifying the solubility of each species in the original chemical equation:

. (Balanced.)

Rewrite species that exist as ions as the corresponding ions to obtain an ionic equation for this reaction. Those species include:

In particular:

Species that do not ionize in water ( in this question) should not be rewritten. Hence, the ionic equation will be:

.

Eliminate ions that appear on both sides of the equation to obtain a net ionic equation. In this ionic equation, those ions include:

Hence, the net ionic equation will be:

.

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.
