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

a. Strong acid, strong base

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 .
