hello people if you add sodium hydroxide to sulfuric acid what salt would you have behind

NaOH + H2SO4 ==> NaHSO4 + H2O

 

I also think hydroxide will be strong enough to remove the second proton to give:

 

NaHSO4 + NaOH ==> Na2SO4 + H2O

 

This reaction will also get very very hot quickly!

umm, sulphuric acid is a stron acid, both of the hydrogens will remove themselves to form H+ ions. these will react with the OH- ions to form water and the Na+ and SO4 (2-) ions will be left in solution.

 

the full rection is 2NaOH +H2SO4 --> 2H2O +Na2SO4

but is this dangerous because it produces chlorine gas

but is this dangerous because it produces chlorine gas

 

It is dangerous for other reasons as Horza pointed out. Please do not attmept this.

there is no chlorine, chlorine cannot be produced.

As i recall, simple acid base reactions are not strong enough to induce atom fusion to heavier elements.

Its dangerous as the reaction can heat up enough to flash boil the water (as I've discovered in the past). So having boiling sulphuric acid flying around is not the safest thing in the world. No you cant get chlorince gas because theres no chlorine in there to start with

Would the reaction be more facile if diluted right down some or done in an ice bath or something? Or if the reagents were added slowly and drop wise from an addition funnel, burette or pipette?

yes, the reaction is perfectly safe as long as you aren't using crazy concentrations like 2M solutions and just dumping the reactants in by the bucketload.

 

do it with 0.05M and add the reactants gradually and keeping it well stirred is perfectly safe.(as long as you wear eye protection to protect against splashes, gloves should be worn too)

there is sodium hydroxide in bleach aint there but there is not enough to do a weakened experiment of this

You have any idea what a strong acid does to hypochlorite? Or do you think making toxic green clouds is somehow cool?

walsh, you have been told time and time again by mods and resident experts not to go adding random things to bleach. Particularly important, as I mentioned before in the IRC room is not to add acid to bleach.

 

DONT DO IT and STOP ASKING

ok i may aswell listen to you as you are a chemistry expert i will not do this but i would like to know what gas is given off:embarass:

with sodium hydroxide and sulphuric acid, none at all.

well why did fuzzwood say there is a cloud of green gas given of

Because bleach contains more ions than just a bit of NaOH.

 

START GOOGLING!!!!

The trick is that there isn't just sodium hydroxide in bleach. There is sodium hypochlorite, and sodium hypochlorite can give off chlorine gas when mixed with the wrong things.

Like acids, in which this happens (although i doubt you care about reaction equations or safety at all)

 

H⁺ + OCl^- --> HOCl

 

5 HOCl -> 2 Cl₂ + ClO3^- + H⁺ + 2 H₂O

fuzzwood dont take it out on me just because im learning get a life

Please refrain from the personal commentary. It's not appropriate to include in the discussion.

Im not taking it out on you, im trying to prevent anything bad happening to you. But since you dont care, why dont you throw every chemical you can find in the household cabinet together and watch the pretty stuff. If you really were learning, you would at least have googled for stuff here instead of being ignorant.

 

EDIT: didnt see there was a 2nd page already

but i looked on a bottle of bleach it sais that THIS CONTAINS SODIUM HYDROXIDE

Just take it from me its main ingredient is sodium hypochlorite. I had to run from it once...

tea contains tannic acid but it's not made entirely of it. some desserts say "may contain nuts" but you don't automatically decide that you have in front of you a pie made entirely out of nuts and nothing else. Sure bleach contains sodium hydroxide. it also contains sodium hypochlorite and a bunch of other things including some stupid colorants to make you think it's somehow cleaner because it leaves a stupid coloured stain on your toilet and some revolting-smelling chemicals which are supposed to make you think you're actually turning your toilet into a pine forest rather than chemically burning the shit out of it.

 

a) don't believe everything you read

b) everyone lies

c) the presence of one thing does not preclude the presence of other things.
