. A conductivity test of a dilute solution of nitrous acid (HNO2 (aq)) has very low electrical
conductivity (the bulb on the tester glows dimly) and the pH is measured to be about
4. The same concentration of a nitric acid (HNO3 (aq)) solution makes the conductivity
tester’s bulb glow brightly and has a pH of less than 1. Explain the difference between
these two acids.
