The picture below shows the relative concentrations of H+ and OH- in a solution. Is the solution an acid or a base?
acid
base
An acid
is a substance that releases H+ ions when dissolved in water
is a substance that does not release any ions when dissolved in water
is a substance that releases OH- when dissolved in water
releases an equal amount of OH- and H+ ions when dissolved in water
Water has a neutral because
it has more H+ ions than OH-
it has more OH- ions than H+
it does not produce any ions
it has an equal amount of H+ and OH- in solution
