Problem

The following model depicts two solutions containing two
. The brightness of each lightbulb represents the conductivity of the solution.
solution A shows 6 acid molecules: 2 which have dissociated into separate H+ and A- particles and 4 which have stayed together as HA molecules. The light bulb above the solution is dim. solution B shows 5 acid molecules: all 5 of them dissociated into separate H+ and A- particles. The light bulb above is bright.
Complete the statements.
  • Solution A is a
    acid. The acid molecules
    dissociate and it is
    conductive.
  • Solution B is a
    acid. The acid molecules
    dissociate and it is
    conductive.
