Dear student
 

To start off, phenol is a mildly acidic, toxic white crystalline solid obtained from coal tar and used in chemical manufacture, and in dilute form (under the name carbolic ) as a disinfectant. The pH of a typical dilute solution of phenol in water is likely to be around 5 - 6 (depending on its concentration). That means that a very dilute solution isn't really acidic enough to turn litmus paper fully red. Litmus paper is blue at pH 8 and red at pH 5. Anything in between is going to show as some shade of "neutral".

With phenol reacts with sodium hydroxide solution it gives a colourless solution containing sodium phenoxide.

 
In this reaction, the hydrogen ion has been removed by the strongly basic hydroxide ion in the sodium hydroxide solution. Hope I helped!
