no you do not always need water to see whether something is acid or alkali
Yes, when you mix an acid and an alkali, a salt and water are typically produced through a neutralization reaction. The acid donates a proton (H+) to the alkali, forming water, while the remaining ions combine to form a salt.
A Armenia's PH helps to know if something is a acid or an alkali
pH 11 is an alkali not an acid
To neutralise an acid you add the equivalent amount of base/ alkali. And for a base/ alkali you add an acid. The reaction that takes place is exothermic, when the temperature stops rising and starts to decrease you know the neutralisation has taken place.
Simple: measuring the pH of the sodium chloride solution.
You use a universal indicator and it turns into whatever colour, according to the PH scale.
acid precipitation is something that aww i dont know
Copper oxide is not considered an alkali. Alkalis are bases that dissolve in water to produce hydroxide ions, while copper oxide is a basic oxide that does not dissolve in water to form hydroxide ions.
A wasp sting is alkali, so if you put an alkali on it, it would not work. To neutralise the sting, you would have to use something acidic, like vinegar, also known as acetic acid. If you want to know more, then I can tell you about bee stings. Bee stings are acidic, so you shouldn't put something acidic on it. Try something alkali, like baking soda, or ammonia. That should help to neutralise the bee sting. Hope that helps x
get some cabbage and crush it up get all the juice out and then pout in little tubes. add what chemicals you want to find out if thy are acid or alkali. the the colour will change and then you are going to have to find out what colour is what as i don't know! x]
From what I know, limestone is alkali, and high pH water would not weather alkali things. For the case of limestone, it might even make the limestone bigger (think so).
u doin this for ms.aubrey 2...
