If oil and water have opposite intermolecular forces, why do they seem to mix at the border between them?

The Chemistry Explanation

Oil and water don't mix because water molecules are not attracted to oil molecules. When the Alka-Selzer tablet is dropped in the oil and water, it sinks to the bottom because it is more dense than oil and more dense than the water.

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.
