Answer:
The pH paper will be required to identify the gas evolved when dilute hydrochloric acid reacts with zinc metal.
Hence the correct answer is option D.
The pH indicator can be termed as a halochromic chemical that is added in very less amounts to any solution so that the pH of solution is visually determined.
A pH indicator detects the hydrogen ions or hydronium ions in Arrhenius model.
