hypothesis: if you can measure the ph of a range of acids and bases using a universal ph indicator, then you can use those values to calibrate a cabbage ph indicator. which method helped you prove this hypothesis? check all that apply. using various concentrations of hcl and naoh to measure a range of ph using an existing scale to determine ph knowing that the cabbage indicator always has the same color at a given ph value

Answer

Answer:

All of the above

Brief Explanation:

Using HCl and NaOH gives pH range data. An existing scale helps measure pH accurately. The color - pH relationship of cabbage indicator is key for calibration.
