What are the spectator ions in the reaction between nitrous acid and sodium hydroxide?

NO₂⁻ and Na⁺

HNO₂(aq) + NaOH(aq) → NaNO₂(aq) + H₂O(l)

H⁺(aq)NO₂⁻(aq) + Na⁺(aq)OH⁻(aq) → Na⁺(aq)NO₂⁻(aq) + H₂O(l)

H⁺(aq)+ OH⁻(aq) → H₂O(l)

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
