@mancool124 Why not? Calcium Carbonate and Sodium Bicarbonate are used as Antacids, they are very useful to the public. Calcium Carbonate can be obtained very easily, through limestone, egg shells, and sea shells.
@orgminyak There are 2 reactions that are occurring, in the first the sodium reacts with the water that is in the test tube along with the hydrochloric acid to produce hydrogen gas sodium hydroxide and heat. In the second the sodium hydroxide reacts with the hydrochloric acid to produce sodium chloride (ie table salt) and water. The sodium chloride is what forms the white film that is seen as the heat that is produced in the first reaction acts to vaporize the salt water formed in the second
Also note that in the first (6M HCl) more heat and hydrogen gas is able to form due to a higher concentration of water than in the second (12M HCl) allowing it to ignite while the second only heats up.
@orgminyak WAY more reactive. To the point of sodium basically being nonreactive to hydrogen (it will only absorb hydrogen at high temperatures around 300C). Meanwhile the reaction of sodium with the hydroxide ion (OH- present at all times in water) is very thermodynamically favorable meaning that it happens easily and quickly.
yes sodium does react vigorously with a hydroxide solution. however your example is incorrect because it is the water in all the acids and any sodium hydroxide solution that the sodium is reacting not the other ions. Plus in the sodium hydroxide example the sodium already in solution would serve to slow down the reaction. A better example wold be potassium hydroxide.
Because in both of the cases in the example it is water that is reacting it does not matter what is in the solution (at least for the purposes of this discussion), but the relative concentration of water that is important. This is shown by the two HCl examples, the 6M solution contains a greater ratio of water to HCl than the 12M solution and can be seen to react more vigorously.
I would think that there is less reaction with the more conc.HCl due to the common ion effect. If Na reacts with 15M to produce NO2 which it lloks like it does what do you think is formed when it reatcs with 6M? NH4+, N2O, NO
if you can get hold of a chunk of sodium, just throw it in water it will explode, acid just made the reaction more violent.
Note: You wont be able get a chunk of sodium because of its violent nature, back then my chemistry teacher can get it in some store, now he say he cant even buy it from chemical retailers as a chemistry teacher. (and yes, he actually throw a chunk of sodium in the lake before)
Because there is a higher concentration of Cl-, it yeilds more NaCl, which creates a kind-of barrier against the acid, also there is more water present in a lesser contrentated acid, leading to a reaction with water aswell as the acid radical.
The bronsted-lowry acid theroy states that an acid will react with water, where water is the base. In this case HCl + H2O ==> H3O+ + Cl-
why is the 6M hcl more reactive than 12M HCL?

you could go on explaining this but when was the last time u saw someone eating limestone :9

Oh, so its more reactive with water than it is with hydrogen ions?

@bonez5656 so u mean that sodium reacts vigorously with hydroxide solution?
Example:
Sodium + Sodium hydroxide faster and more vigorously then Sodium + Sulphuric acid ?

Yes, potassium explodes.

Potassium is also like this because it is also in group IA like sodium.

BRAVO!
That's way more fun.
Next time drop potassium into sulphuric acid.

The Cl- doesn't take part in the reaction at all. We start with Cl- and we finish with Cl-. The reaction is:
2Na(metal) + 2H+ = 2Na+ + H2(gas)
P.S. You can't spell yields, concentrated or theory. Your chemistry is crap too.
