Will give medal and fan!! How could a student determine whether an unknown chemical is an acid? Test the hydrogen ion concentration in the sample. Measure the boiling point of the sample. Weigh the sample before and after adding salt. Determine whether the sample has surface tension.

    Which experiment best shows water’s ability to act as a solvent? Raise the temperature of water and record its boiling point. Freeze a flexible vessel of water and watch it expand. Pour an ionic solid into water and see if it vanishes. Place a leaf on top of the surface of water and see if it sinks.

    c seems like the most reasonable since a solvent dissolves other chemicals
