To identify which solution is a base, we need to look for a solution with a pH greater than 7.
Since Solution D has a pH of 9, it is the only solution that is basic.
Therefore, Lila should identify Solution D as being a base.
When a hydrogen ion (H⁺) interacts with a water molecule (H₂O), it forms a hydronium ion (H₃O⁺).
Therefore, the correct response is hydronium ion.
A property of bases is that they feel slippery.
Thus, the correct response is feels slippery.
