    In the last experiment when we added HCl to NaOH and it turned pink to colorless how can we be sure if it neutralized only as it can also be acidic as phenolphatalein indicator turns colorless when in contact with acid?

    you have just reacted NaOH with HCL in the last section of the video and they reacted with each other to form compound i.e NaCl+H2o
    that means that the product is saltwater can you tell me the product form by these two compounds is safer to drink??
    NOTE-- phenolphthalein is also added to the solution

      Yes, the product is saltwater, but it is not safe to drink. Here's why :
      1. As you mentioned, phenolphthalein is also added to the solution. Earlier, it was used as a laxative, but its use has been reduced due to concerns over its carcinogenicity(promotion of formation of cancer). It is a chemical which may or may not be harmful.
      2. Also, remember that all of the HCl and the NaOH may not have reacted completely with each other (Phenolphthalein indicates only bases-some acid might be remaining in excess). Hence, it can be very harmful.
      MY ADVICE - DON'T TRY DRINKING IT.

      Happy if I was able to help :)

    Why can we use aqueous solutions to form soluble salts but not use solid to react with aqueous solutions? Like when
    NaOH (aq) + HCL (aq) -> NaCL (aq) + H20 (l)
    NaCL is soluble, and both the acid and alkalis used are aqueous. How?? I thought it worked only like this
    (s) + (aq) -> (aq)

      Bees don't usually sting unless they're aggravated by someone or something, because stinging someone causes their "stinger" to be pulled out, and displaces all of their internal organs, meaning the bee dies after stinging. They only use this as a last defense mechanism, to protect the hive, or otherwise. I think that the picture was taken from some article talking about this, and they were just using the picture as a reference.

      I hope that helps :)
