Why 7 is the middle number for PH between acid and base?
The number is the middle number for PH between acid and base because it is neutral. This is number that falls in between 0 and 14.
Explain the relationship between the strength of an acid and its conjugate base and a base and its conjugate acid?
The difference between acids and bases is that acids have mare hydrogen ions then hydroxide ions ( and it has to be in an aqueous solution). *ACID* if it has more hydrogen ions then hydroxide ions then it is an acid. *BASE* if it has more hydroxide ions then hydrogen ions it is a base. ALSO... if the substance you have has a PH rating you can determine if it is a base or acid…
Explain how the relationship between the strengths of an acid and its conjugate base and of a base and its conjugated acid?
When a strong acid and a strong base mix, all acidic protons will react with every basic molecule until one or the other runs out. The curve for a titration of a strong acid with a strong base will change slowly at first, and dramatically when the equivalence point (where the number of moles of acid is equal to the number of moles of base) is reached. The reaction, like all acid-base reactions, is fast.
