Answer: Option (D) is the correct answer.

Explanation:

An electronic device which is used to measure hydrogen ion activity is known as a pH meter.

That is, a pH meter is useful in detecting or knowing the acidity (due to $H^{+}$ ions) or alkalinity (due to $OH^{-}$ ions) of a solution.

Thus, we can conclude that out of the given options it is true about a pH meter that it can be used in any acid-base titration.

Answer the following questions that relate to electrochemical reactions. (a) Under standard conditions at 25˚C, Zn(s) reacts wit

Elanso [62]

Answer:

0.48 V

Explanation:

Zn(s) ------------> Zn^2+(aq) + 2e. Oxidation half equation (-0.76V)

Co^2+(aq) + 2e-----------> Co(s). Reduction half equation (-0.28)

Zn(s) + Co^2+(aq) -------------> Zn^2+(aq) + Co(s) overall redox equation

Zinc is the anode while cobalt is the cathode.

E°cell= E°cathode - E°anode

E°cell= -0.28-(-0.76)= 0.48 V
