acid

substance that releases H+ ions and produces hydrogrum ions when dissolved in water

base

substance that accepts H+ ions and produces hydroxide ions when dissolved in water

indicator

compound that changes color at at different pH value when it reacts with an acid or basic solution

does not produce a new substance - moleclues are the same

chemical change

produces a new substance - molecules change
