Rödkåljuice innehåller en naturlig pH-indikator som ändrar färger beroende på lösningens surhet. Röda kåljuiceindikatorer är enkla att göra, uppvisar ett brett utbud av färger och kan användas för att göra dina egna pH-pappersremsor. Indicators are substances whose solutions change color due to changes in pH. These are called acid-base indicators. They are usually weak acids or bases, but their conjugate base or acid forms have different colors due to differences in their absorption spectra. pH indicator strips with 4 pads, pH 0,0 - pH 14,0, Interval: 1 pH, 100 strips/pack, 10 packs : 1 591:- Köp.
