Let's say you have a mixture for which you want to check the composition. Unfortunately, after quite a while, and several TLC analyses using our system, no spots have moved up the plate. What change could you make in the TLC system to try to get at least one compound in the original mixture to move up the plate?
1- try a more polar solvent
2- try a less polar solvent
3- try a more polar adsorbent

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.
