Red cabbage juice indicator. Red cabbage juice indicator solution was added to several test tubes containing solutions with varying pH values,left to right: 1 through 13 in steps of 2. Hydrochloric acid of varying concentrations was used to prepare acidic solutions (pH<7),sodium hydroxide of varying concentrations was used to prepare alkaline solutions (pH>7),and neutral buffer solution was used for pH=7 | |
