A laboratory technician bubbles sulfur dioxide (SO2SO_2SO2) gas and dinitrogen pentoxide (N2O5N_2O_5N2O5) gas into separate flasks containing distilled water. A strip of blue litmus paper is then immersed into each flask.
State the final colour of the litmus paper observed in both flasks and explain this observation by referring to the chemical nature of these oxides and the specific ions responsible for the change.
