Nitrous acid<span> dissociates as follows:
</span>
HNO₂(s) ⇄ H⁺(aq) + NO₂⁻(aq)
According to the equation, an acid constant has the following form:
Ka = [H⁺] × [NO₂⁻ ] / [HNO₂]
From pH, we can calculate the concentration of H⁺ and NO₂⁻:
[H⁺] = 10^-pH = 10^-2.63 = 0.00234 M = [NO₂⁻]
Now, the acid constant can be calculated:
Ka = 0.00234 x 0.00234 / 0.015 = 3.66 x 10⁻⁴
And finally,
pKa = -log Ka = 3.44
Because if they are submerged in the solvent, they would dissolve! This would prevent them from seperating and not allow you to actually record anything
Answer: Option A. 6.022 x 10^23
Explanation:
Answer:
Explanation:
so we have to solve it or just answer it?
The electrons will move more rapidly resulting in a higher pressure even at a consistent volume
