When the system turns pink, then the end point has been attained.

<h3>What is the end point?</h3>

The end point or the equivalence point is the time when the reactants have undergone transformation in accordance with the reaction equation. The reaction in this case is; HCl + NaOH -----> NaCl + H2O.

We know that phenolphthalein is colorless in acid but red in a base. The color at end point is pink. Thus, when the system turns pink, then the end point has been attained.

morpeh [17]

Answer:

Mn(s)/Mn^2+(aq)//Co^2+(aq)/Co(s)

Explanation:

In writing the cell notation for an electrochemical cell, the anode is written on the left hand side while the cathode is written on the right hand side. The two half cells are separated by two thick lines which represents the salt bridge.

For the cell discussed in the question; the Mn(s)/Mn^2+(aq) is the anode while the Co^2+(aq)/Co(s) half cell is the cathode.

Hence I can write; Mn(s)/Mn^2+(aq)//Co^2+(aq)/Co(s)
