The equivalence point in a titration refers to the point when the mL of the acid equals the mL of the base.
the molarity of the acid used in the reaction equals the molarity of the base used in the reaction.
the number of moles of one reactant reacts completely with the moles of the other reactant.
the acid in the flask turns clear.

a basic solution is an aqueous solution containing more oh-ions than h+ions. in other words, it is an aqueous solution with a ph greater than 7. basic solutions contain ions, conduct electricity, turn red litmus paper blue, and feel slippery to the touch.

explanation:

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."
