You always have to know what type of chemical you are using, because some chemicals are very sensitive. If you mix wrong chemicals together, you can produce some deadly gases. If you inhale the gas, it can cause death! In many labs, it is important that you "add acid". For example, if you add a very concentrated acid into water, nothing really will happen; but if you add water to the acid, it will react instantly and then it'll boil and spit everywhere. Consequently, the acid can get on your skin.

6 What happens when an acid is dissolved in water?
it is still acid but weaker because the water-acid base ratio grows depending on how much water or acid base there is You need water to make acid (e.g. Hydrogen Chloride itself is not acid, it is an acid base, but when dissolved in water it is a very strong acid)
What does it mean to neutralize a solution and how can this be done?
to get a pH of 7(neutral pH) you need to add a base solution to an acid solution and vice versa until you eventually approach a pH of 7
Can Neutralize a base physical or chemical?
Add a strong base to strong acid and you will neutralize it. Similarly, add a strong acid to a strong base and it will be neutralized. For example:- HCl + NaOH ----> NaCl + H2O You add a strong base to a strong acid and get a neutral salt and water.
Do You need to have water present to see if something is an acid or an alkali.?
no
Is NH3 an acid or a base?
well NH3 is a base that reacts with H2O to get NH4 + OH- NH3+ H2O-->NH4+ + OH- A conjugate base is the species formed when a Bronsted- Lowry base accepts a proton. NH4+ is the conjugate acid of NH3
Do you need water to know if something is an acid or alkali?
no you do not always need water to see whether something is acid or alkali
Why do you need indicators of chemical change?
To indicate the change of its Ph nature either from acid to a base or a base to an acid

What are the acceptable ranges for PH?
pH ranges from 1 (acid) to 14 (base). As far as acceptble range, you need to make clearer what else you need to know...like pH range of blood.
Do You need to have water present to see if something is an acid or an alkali.?
no
What is the pH for an acid for a base?
you learnt in school so why do you need answers from the websit
What do you neutralize battery acid with?
you would need a base in neutralize since it is an acid, but you would need to the acid's hp number. Bleach would probably work, but don't try it get medial help.
Why can a buffer only buffer against a small amounts of acid or base?
A strong acid and a strong base will react together to produce a neutral salt. E.g., HCl (strong acid) and NaOH (strong base) will react together to form H20 and NaCl (salt). The salt is neutral (if you dump table salt into water, the solution will be neutral) this is because the Na+ and Cl- are perfectly happy being charged atoms. If you have something that doesn't really like to be ionized, which is a weak acid or base (for example acetic acid, (vinegar) which is only 1.1% ionized (charged) in a water solution) will only be ionized if something forces it to be ionized, i.e., a strong acid or base. When there is a mixture of a weak acid and its conjugate salt (or weak base and its conjugate salt) a buffer is formed. This is due to the fact that if you add some strong acid it will simply react with the conjugate salt, and if you add some strong base it will react with the weak acid. This is how they "buffer solutions" by keeping things pretty balanced. So to answer your question, a buffer must contain something that is only weakly reactive, and can react further when the need is present. A strong acid/base will totally react, so there is nothing left over to do any buffering.

well NH3 is a base that reacts with H2O to get NH4 + OH- NH3+ H2O-->NH4+ + OH- A conjugate base is the species formed when a Bronsted- Lowry base accepts a proton. NH4+ is the conjugate acid of NH3
Can you use acetic acid for TAE buffer?
you'll need a salt as well. Buffers are made up of an acid/base and its salt.
