The wastewater from a chemical plant manufacturing sulphuric acid was thought to be contaminated with cadmium. a 25 ml. aliquot of the water was adjusted to ph 5 and an ion selective and saturated calomel reference electrode was placed in the solution. the potential difference between the electrodes was-0.110 v after addition of 5.00 ml of a 3.40 x 103 m cd" standard, the potential difference was-0.104 v. calculate the concentration in ppm of cd2 in the wastewater sample.

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.
