Interpretation : The possibility of a concentrated weak acid is to be explained.
Concept Introduction : Acids are substances that contain hydrogen and ionize to produce hydrogen ions
Answer to Problem 80A
It is possible to have a concentrated weak acid because the concentration deals with molarity and acid strength deal with ionization.
Explanation of Solution
Weak acids have a high concentration of undissociated species in the solution since they don't entirely dissociate. Following the equation below, a monoprotic acid will dissociate.
A concentrated acid solution has a very high acid percentage.
A concentrated solution implies a high degree of purity rather than a high degree of dissociation.
It is possible to have a concentrated weak acid because strength is based on ionization, whereas concentration is dependent on molarity.
