Depending on the type of acid/base (Arrhenius, Bronsted, Lewis), the acid donates protons and a base doesn't but accepts protons, or the base donates OH- and the acid doesn't, or the acid accepts a pair of electrons and the base donates a pair of electrons. They are just different, that's why.
What else can I help you with?
What happens when a strong acid and a strong base are mix together?
They react by forming water and a salt which is either soluble thus ionised, or as insoluble precipitate.
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.
What is sodium hydroxide and hydrochloric acid the same as?
Sodium hydroxide is a base and hydrochloric acid is an acid. Both are not same.
What is the reaction when acid and base react in an exchange reaction to form salt and water?
When an acid and base combine, they participate in a neutralization reaction forming water and a salt.
Is the compound HCI an acid or base?
It is an Acid, known as Hydrogen chloride (and Hydrochloric acid, when it is dissolved in water)
Is nitrogen oxide an acid?
Nitrogen oxide is not considered an acid because it does not dissociate in water.
Is SO2 an acid or base?
SO2 is an acidic oxide because it can react with water to form sulfurous acid.
Is hydrochloric acid the only acid which reacts with carbonates?
No, any strong acid will react with carbonates.
How can a weak acid be neutralized effectively?
A weak acid can be neutralized effectively by adding a strong base to it. The strong base will react with the weak acid to form water and a salt, which will result in the neutralization of the acid.
What happens when a strong acid and a strong bace react?
A strong acid dissolves to form H+ and an anion, and a strong base dissolves in water to form OH- and a cation. When they react, the H+ and OH- react, forming water (and usually a large amount of heat) the anion and cation may either react to form a precipitate (if the reaction yields an insoluble compound) or they remain suspended (if their compound would yield an already soluble compound). A strong acid when react with a strong base, a neutral compound is formed with the evolution of heat.
When equivalent amounts of a strong acid and a strong base react the results is?
When equivalent amounts of a strong acid and a strong base react, they neutralize each other to form water and a salt. The pH of the resulting solution will be 7, indicating it is neutral.
Why does sulphuric acid react easily with sodium hydroxide and not hydrochloric acid?
Sulfuric acid reacts easily with sodium hydroxide to form sodium sulfate and water because sulfuric acid is a strong acid and sodium hydroxide is a strong base. This reaction occurs because both acids and bases react to form water and a salt. Hydrochloric acid may not react in the same way because it is a weaker acid compared to sulfuric acid.
Does hydrogen react with water or acid?
Hydrogen does not react with water. In an acid, hydrogen can react to form hydrogen gas and a salt.
The ionic compound produced when a strong acid and strong base react is called a what?
The ionic compound produced when a strong acid and strong base react is called a salt. It is formed as a result of the neutralization reaction between the acid and base, where the H+ ions from the acid combine with the OH- ions from the base to form water, leaving behind the positively and negatively charged ions of the salt.
What is the pH at the equivalence point of a strong acid-strong base titration?
The pH at the equivalence point of a strong acid-strong base titration is 7, which is considered neutral because the strong acid (e.g., HCl) and strong base (e.g., NaOH) react completely to form water and a salt.
What metals dont react with acid oxygen or water?
A metal that does not react to acid, oxygen or water does not exist.
What happens when a strong acid and a strong base react?
When a strong acid and a strong base react, they neutralize each other to form water and a salt. The reaction is typically very exothermic, meaning it releases heat energy. The resulting solution will have a pH of 7, indicating it is neutral.
