Answer is: pH <span>of a 0,01 M solution is 2.
c(HNO</span>₃) = 0,01 M = 0,01 mol/L.
pH = -log(c(HNO₃).
pH = -log(0,01 mol/L).
pH = 2.
pH<span> is a numeric scale used to specify the </span>acidity<span> or </span>basicity<span> of an </span>aqueous solution<span>. If pH is less than seven, than solution is acidic and if pH is greater seven, solution is basic, if pH is equal seven, solution is neutral.</span>
This question seems to be an essay question from experiment. Different solution of oxidizing agent will have different strength. Sulfuric acid or H2SO4 is weaker oxidizing agent when compared to nitric acid (HNO3). In this case, if you subtitute the H2SO4 you wouldn't be able to get the same result for the experiment.
The relation between the elements electro negativity, atomic radius, and ionization energy levels.
Answer: 368 grams of sodium reacted.
Explanation:
The balanced reaction is :

According to stoichiometry :
2 moles of
are formed from = 2 moles of 
Thus 16 moles of
are formed from=
of 
Mass of 
Thus 368 grams of sodium reacted.
That would be 0.26 liters
Hope it help!
