Question

If the resulting pH is 7, it was most likely a titration. a. Strong acid, strong base b. Strong acid, weak base c. Weak acid, strong base d. Weak acid, weak base

Answer 1

a. Strong acid, strong base

Step-by-step explanation:

pH = 7 , is the neutralization point , where , the concentration of Hydronium ions ( H⁺ ) becomes equal to the concentration of the hydroxide ions ( OH⁻ ) .

In case of strong acid and strong base ,

The acid and the base will dissociate completely , and will give the corresponding ions , i.e. , the ( H⁺ ) and ( OH⁻ ) , which will combine to give water , which has a pH of value 7.

In case of weak electrolytes , there wont be complete dissociation and the ions generated wont be enough to generate water of pH 7 .
