A reversible reaction is a chemical reaction that may proceed in both the forward and reverse directions. In other words, the reactant and product of one reaction may reverse roles, without adding chemicals.
Symbolically,
- products C and D are produced from reactants A and B, but C and D can react to form A and B.
In an irreversible reaction the equilibrium states are shifted so close to either the products or the reactants that the reaction effectively does not have an equilibrium between the products and the reactants. Hence, irreversible reactions can be viewed as an extreme, "special case" of reversible reactions. Irreversible reactions are often called "spontaneous" or "favorable". These reactions are usually entropically driven, as opposed to thermodynamically driven. In an irreversible reaction, there is generally a great increase in entropy.

A) I would remove the word "relative" from your answer. It is a scale that measures the acidity or alkalinity of a solution. B) A strong acid, by definition, is an acid that dissociates completely in solution. I've never heard the term "dilute acid" before, but if I had to guess, it means a "weak acid", which is an acid that does not completely dissociate in solution. Either way, your answer must be wrong, because nothing called an "acid" can have a pH over 7. The word "acid" MEANS pH < 7. I would go with "a strong acid dossociates completely in solution, while a dilute acid does not". C) You misread this question. You've listed 1 difference as two in each case. You have this: 1) Acids turn blue litmus red, while bases turn red litmus blue 2) Bases neutralize acids, while acids neutralize bases 3) Well, both strong acids and strong bases conduct electricity in solution, so this answer is wrong no matter how you word it. Some more differences include: -Bases have a slippery texture (like soap), while acids do not -Acids have a pH under 7, bases have a pH over 7 (are you allowed to use this one?) -Acids are proton donors, bases are proton acceptors (you may not have learned this yet). D) You're correct already I hope I've been helpful!

In controlled conditions,the products eg sodium chloride and water can be coverted into alkali by electrolysis.The alkali and acid reaction giving salt and water is not reversible.Salt and water does not change to alkali and acid,under any normal conditions.

Looking at the answers makes me wonder, observe what happens when sulphuric acid is introduced to a bi-carbonate of soda solution, how would you go about reversing that reaction?

Yes, it does in a few cases of a weak acid and an alkali...

Yes it can - BUT only if there is no reaction that occurs that causes a stable product to be produced that can not be easily broken apart.

Yes,by titration.

does this maybe have anything to do with equilibrium? maybe not just a shot in the dark.
