Ascientist observes that after mixing a solid powder into water, the ph of the newly formed solution is 2.7. what can he infer from this observation?
the solution contains an indicator that has a ph of 2.7.
the solid powder contained hydrogen ions.
the ph indicator was used incorrectly.
the powder increased the hydrogen ion concentration of the solution.
