Answer:
When equal volumes of hydrochloric acid (strong acid) and sodium hydroxide (strong base) solution of same concentration are mixed, the result is salt and water. This is a neutralisation reaction. The aqueous solution of NaCl is neutral with pH 7. The colour of this solution obtained is yellowish green
