Assuming that you mean 10^-4 M then this would be basic and would have a pH of 10.
pOH = -log[OH].
So pOH = 4
pH=14-pOH
pH = 10
Chloride ions Cl –(aq) (from the dissolved sodium chloride) are discharged at the positive electrode as chlorine gas, Cl 2(g) sodium ions Na +(aq) (from the dissolved sodium chloride) and hydroxide ions OH –(aq) (from the water) stay behind - they form sodium hydroxide solution, NaOH(aq)
Answer:
Is pink in base solution, it provides a visual signal that a solution has changed from acid to a base, is colorless in acid solution.
Explanation:
As all the indicator, phenolphtalein has the property that turns pink when the solution that you have reaches a value of a pH of 9 or above. From 0 to 8 in a pH scale, is colorless. This point in which an indicator changes is it called equivalence point.
