The Ka of a monoprotic weak acid is 6.08 × 10-3. What is the percent ionization of a 0.187 M solution of this acid?
If you put 120 volts of electricity through a pickle, the pickle will smoke and start glowing an orange-yellow color. The light is emitted because the sodium ions in the pickle become excited; their return to the ground state results in light emis..
