    Yehey! It's time for our Science Experiment!

    I have some few questions before our experiment will happen, I guess next week.:)

    We are going to taste a diluted hydrochloric acid. Is hydrochloric acid a scientific name for muriatic acid?:p

    What do you think guys is the taste of hydrochloric acid? Is it safe? Or what?

    Don't worry our Science teacher will be there at our lab together with us.:D

    How to find the volume of an irregular shaped items?

    It is like

    1st, Record the volume of water.
    2st, put the irregular shaped item on water in beaker.
    3rd, minus the volume of water (only) by the new volume (the water volume plus the irregular shaped item)
    4th, is that the answer already? We should put ^3, right? Like 3 cm^3:)

    What do we call like that? Water displacement????:confused:

    Can I use Hydrochloric acid as an alternative acid for Sulfuric acid for a Voltaic Battery? Will the Hydrochloric acid react If I put zinc strip, copper strip, and a bulb? What will happen?

    Thanks so much.:D

    Hydrochloric acid is also called muriatic acid or muric acid.
    Around 0.5% of hydrochloric acid is found in gastric acid a type of digestive fluid which help us in digesting food.It forms inside our stomach.
    Let your teacher guide you on this...

    In general we called it Archimedes principle ,but this is also known as Displacement under Fluid Mechanics.

    Hydrochloric acid (HCL) is not an alternative acid for Sulfuric acid (H2SO4),but for voltaic cell you can use any acid,but the reaction will differ and the amount of voltage will also differ.

    HCL is highly corrosive,so its too dangerous it can burn your skin and tissue,and it forms acidic mists which is also very dangerous don't try to smell it.

    Good luck and be safe.

    Sounds like a very dangerous experiment to me....

    As debjit625 said, hydrochloric acid is what you have in your stomach to digest food (stomach acid) and is highly corrosive. The reason it does not hurt you is because it is contained within the mucus-lined stomach. However, if any of it seeps back into your esophagus, it can cause severe damage. Ever hear of heartburn? That is generally caused by acid backing up, and if it happens often, can lead to acid reflux disease (basically it eats away at your esophagus and can damage it severely).

    Anyway, hydrochloric acid is very corrosive and can even melt through some times of metal. Here's a video of a few different metals being put into hydrochloric acid:

    It can even melt flesh right off your bone, so please be very careful, and listen to your teacher. This is very important to your safety.

    Dude, why are always attracted to more dangerous things?

    You can make an acid/metal battery that can easily power an LED using some solid copper wire, two zinc coated nails and a couple of lemons.

    No. I promise all of you, all the questions related to dangerous stuffs I asked, I don't do in real life. I just ask but not do. I can't buy them any where because it is not allowed, you need to have business or school.

    But the tasting Hydrochloric acid is requested by my teacher. :D

    If the teacher is supervising, it is fine. We've all vomited and survived and you will almost certainly be tasting hydrochloric acid which is less concentrated than that (and it won't taste as bad because it doesn't have other nasties like bile in it).

    I don't believe hydrochloric acid has either an odor or a taste. It'll probably just taste like you're drinking water (if it's fully diluted--otherwise you won't taste it because your tongue would be burnt off :p ).
    That's just my guess, anyway.

    As per me I learnt it in school "Acids taste sour".

    Good Luck

    Okay, just did a bit of research and you're right. Hydrochloric acid has a sour and slightly bitter taste.
