Which solution containing one mole per dm 3 of the compound will have the lowest pH? A. Ethanoic acid B. Hydrochloric acid C. Sodium chloride D. Sodium hydrogen carbonate

Explanation:

A. Ethanoic acid-acetic acid being weak acid dissocated weekly and turns solution to weakly acidic, ph will be between 4-7,

B. Hydrochloric acid - the solution would be acidic- with lots of H+ ions, Ph will be between 1-4,

C. Sodium chloride - solution prodcued netural Na+ and Cl- hence wont affect ph of solution will be equalt to 7.

D. Sodium hydrogen carbonate-NaHCO3 is weak base and the PH will be above 7,
