pH below 7 always is acid, base has pH above 7.
alkaline obviously! strong acid + strong base= neutral strong acid + weak base= acidic weak acid + strong base= alkaline
B. a strong acid
It would turn red in strong acid, orange/yellow in a weak acid, green in a neutral solution, blue in a weak base and purple in a strong base
Strong acid is an expression in relation with the chemical properties of the acid and is used also in physical chemistry; dilute is a term only in relation with the concentration of the acid. Consequently strong acid and concentrated acid are not synonyms and a strong acid can be diluted.
A solution containing either a weak acid or a weak acid its saltor a weak base and its salt?

Ephedrine sulfate will act as a weak acid in solution because yes it is the salt of a weak base (ephedrine) and a strong acid (sulfuric acid)
B. a strong acid
Strong acid > Weak acid > weak base > strong Base. Will produce the most hydronium ions to the least hydronium ions.

A buffer solution is one involving a weak base/weak acid with its conjugate acid/base. In a buffer solution, the pH must be changed to only a small amount. Thus, any solution with a STRONG acid or a STRONG base is not a successful buffer solution because there would be a relatively large change in the initial pH.

It depends which part of the stong acid concept you are concerned with: A weak acid is the opposite of a "strong" acid A strong base is the opposite of a strong "acid" A neutral solution is the oppposte of a strong acid (a reactive solution)
CoCO3 (Cobalt II carbonate) would be a weak base.
The conjugate base of a weak acid is always a strong base
Barium fluoride can be considered to be the salt of barium hydroxide (a weak base) and HF (a strong acid). And a solution of BaF2 will be weakly acidic.
