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.
To determine the concentration of the acid (H2SO4) in a titration, you will need to know the volume of the acid used, the volume of the base added, and the molarity of the base. By using the balanced chemical equation of the reaction and the volume of the acid and base used, you can calculate the concentration of the acid.
Use this to analyse the unkown and variables:Ca*Va = Cb*Vb in which:C = concentration (mol/L = mmol/mL)V = Volume (L or mL)subscripts: 'a' = acid, 'b' = baseWanna know Vb ? well find the other three variables to calculate: (Ca*Va)/Cb = Vb (with the same unit as used for Va)
Its an acid since it has a positive hydrogen ion. This is know because the polyatomic OH its charge is -1 and to balance the charge you'd need +1 being the hydrogen Actually HOH is another common form of writing H2O (pure water). Since water has pH level of 7, it is neutral, neither a base, nor an acid.
Litmus paper only indicates the presence of an acid or a base, not the strength. The color change to red indicates an acid, while blue indicates a base. To determine strength, you would need to use a pH indicator or perform a more thorough chemical analysis.
To neutralize the 25ml of 3M acid, you would need to find the number of moles of acid present, which is 25ml * 3M = 75 millimoles. Then, you would need the same number of millimoles of the 8M base to neutralize it, so you would need 75 millimoles / 8M = 9.38ml of the 8M base.
no you do not always need water to see whether something is acid or alkali

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.
you learnt in school so why do you need answers from the websit
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.
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.

You cannot convert an acid to a base directly. Acids and bases are different types of compounds with specific properties. You would need to neutralize the acid by adding a base to it in a chemical reaction to form water and a salt.
you'll need a salt as well. Buffers are made up of an acid/base and its salt.
