walsh155 Posted October 23, 2009 Posted October 23, 2009 hello people if you add sodium hydroxide to sulfuric acid what salt would you have behind
Horza2002 Posted October 23, 2009 Posted October 23, 2009 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!
insane_alien Posted October 23, 2009 Posted October 23, 2009 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
walsh155 Posted October 23, 2009 Author Posted October 23, 2009 but is this dangerous because it produces chlorine gas
SH3RL0CK Posted October 23, 2009 Posted October 23, 2009 but is this dangerous because it produces chlorine gas It is dangerous for other reasons as Horza pointed out. Please do not attmept this.
insane_alien Posted October 23, 2009 Posted October 23, 2009 there is no chlorine, chlorine cannot be produced.
Fuzzwood Posted October 23, 2009 Posted October 23, 2009 As i recall, simple acid base reactions are not strong enough to induce atom fusion to heavier elements.
Horza2002 Posted October 24, 2009 Posted October 24, 2009 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
DrP Posted October 24, 2009 Posted October 24, 2009 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?
insane_alien Posted October 24, 2009 Posted October 24, 2009 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)
walsh155 Posted October 24, 2009 Author Posted October 24, 2009 there is sodium hydroxide in bleach aint there but there is not enough to do a weakened experiment of this
Fuzzwood Posted October 24, 2009 Posted October 24, 2009 You have any idea what a strong acid does to hypochlorite? Or do you think making toxic green clouds is somehow cool?
hermanntrude Posted October 24, 2009 Posted October 24, 2009 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
walsh155 Posted October 25, 2009 Author Posted October 25, 2009 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:
insane_alien Posted October 25, 2009 Posted October 25, 2009 with sodium hydroxide and sulphuric acid, none at all.
walsh155 Posted October 25, 2009 Author Posted October 25, 2009 well why did fuzzwood say there is a cloud of green gas given of
Fuzzwood Posted October 25, 2009 Posted October 25, 2009 Because bleach contains more ions than just a bit of NaOH. START GOOGLING!!!!
Cap'n Refsmmat Posted October 25, 2009 Posted October 25, 2009 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.
Fuzzwood Posted October 25, 2009 Posted October 25, 2009 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
walsh155 Posted October 25, 2009 Author Posted October 25, 2009 fuzzwood dont take it out on me just because im learning get a life
swansont Posted October 25, 2009 Posted October 25, 2009 Please refrain from the personal commentary. It's not appropriate to include in the discussion.
Fuzzwood Posted October 25, 2009 Posted October 25, 2009 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
walsh155 Posted October 25, 2009 Author Posted October 25, 2009 but i looked on a bottle of bleach it sais that THIS CONTAINS SODIUM HYDROXIDE
Fuzzwood Posted October 25, 2009 Posted October 25, 2009 Just take it from me its main ingredient is sodium hypochlorite. I had to run from it once...
hermanntrude Posted October 26, 2009 Posted October 26, 2009 but i looked on a bottle of bleach it sais that THIS CONTAINS SODIUM HYDROXIDE 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.
