Nitrogen Dioxide, Nitrogen Oxide is colorless. Nitrogen Dioxide actually forms an equibrillium with Dinitrogen Tetraoxide, which is also colorless. At a lower temperature, there will be more N2O4 and the color lighter brown :)

Its because Cl- ions are released so rapidly in the high molar HCl acid they form NaCl very fast. To fast for the Na to react with the H2O. The lower molar acids have more water, and like you said, Na + H2O is a very violent reaction. In other words Na wants the Cl more than the H2O, and High molar HCL has more CL to react with

@tomyo669 HCl is hydrochloric acid. HNO3 is nitric acid. The sodium reacts with those substances to from sodium chloride (NaCl) and sodium nitrate (NaNO3) respectively. Hydrogen gas is also produced

Actually, IIRC, sodium violently reacts with pure water without acid. The 12M HCl reaction is very interesting in that there is no violent reaction (just salt formation I guess), whereas the 6M solution may not be strong enough to nullify the additional reaction of sodium with water. I have no idea about the HNO3. I'm certain it proves something.. but I'm no chemistry buff.

@fava1300 it brown gas you can see is NO2 Nitrogen Dioxide

It doesn't burn your skin. You absorb it into your bloodstream through your skin and you die. I can see where there is confusion though lol.

HF is a weak acid lol. Try HClO4 lol. That way the salt is flamable too!! :D

hold on sodium is na right there is no na in any of those just n

ok ..... first of all ... wouldn't the 12M HCL be more concentrated then the 6M but it reacted slower.... that doesn't make much sense........and what is first to react.... what is that suppose to prove ?? I don't think this experiment proves anything

wow lol the highest concentration our school has is HCl 2M

No Man .. It's Sodium reacting with four acids Example: In the first you got Na reacting with HCl
