Why is methyl orange used instead of phenolphthalein?
WebJan 4, 2016 · The pH at this point isn't alkaline enough for phenolphthalein to become colourless, since there's still base ( N a X 2 C O X 3) present in the solution. Then N a X 2 C O X 3 reacts. When all the C O X 3 X 2 − becomes H C O X 3 X −, the pH is given by: p H = p K a 1 + p K a 2 2 which is approximately 8.3.
