  • Now its H2O + NaCl :D

  • thanks a lot ! ^^

  • where is the pheolphthalien?

  • This was so helpful :)

    But it kinda sounds like you're on helium :P

    In a good way? xD

  • muy buena la explicacion de la neutralizacion...pero no cumple con las normas de seguridad para trabajar en un laboratorio donde estan los guantes que protegen las manos??? jaja y ella es una quimica???

  • In my class, all we do is read and take notes about it. I know realized looking at it helps me understand way more than by note taking.

  • Question: why is there an increase in the neutralized substance? Like if you mixed 50 mL HCl and 50 mL NaOH, why would you get more than 100mL of the neutralized substance?? (because you do)

  • @bracelet123 Matter is neither created nor destroyed in a reaction, therefore you will not get any more in the final product. It is called the conservation of matter.

    Hope this helps

  • I wish chemistry was like this on my school..

  • I <3<3<3<3 chemistry !!!!!

  • Ooh, now i get it..so does this happen if i mix any acid and any base? do i always end up with a salt and water? what if i tried another strong acid and another base?

  • @Anae420 you end up with always water, salt, and sometimes another product

  • Great!!! Helped me understand the topic much more

  • if hcl gets on your skin, can u remedy it with naoh?

  • @5hak3itup And burn yourself twice? Go ahead :D

    Just use water.

  • @Kukkaloota you gotta impress the ladies with your manlyness! roaar! haha

  • thxz i have a lab tommoro its preaty basic but this answered my questions.

  • geez that was sooo cool, I have a test tomorrow on acid base titration

  • Great video, help very much appreciated. =]

  • well thank you

  • It doesn't reveal very much of the theory behind acid-base reactions in water. The demo itself is a good old classic, I would have prefered using beakers though.

  • what difference does it make....beaker or not, its still the same thing.

  • Good video.

  • The pink comes from the OH indicator of phenolphthalein and it only disappears when your acid concentration equals to your alkaline (basic) concentration.

  • Hmm.. How does the pink disapear?
