Natural pH Indicators: Make a pH indicator using beetroot or cabbage!

Natural pH indicator foods change colors as the pH of the solution changes. From purple to blue, green, even yellow! Learn how to make a pH indicator with beetroot and compare it to the color changes we see in purple cabbage. This is an easy and fun kids chemistry project that you can do with...

Thank you! Interesting information, I think my younger son will enjoy doing this!

Hmm... would those litmus strips sold at the pharmacy work? They have a range from 5 to 9 pH.

I believe that they would work. And you could also compare their results with the beet juice test.

I checked the pH. I took soil from a depth of 15-20 cm. I poured water with a pH of 7, stirred it well, let it stand for 30 minutes, and filtered it through a cotton filter. I checked it with the medical tests I posted above. Results:
1. Purified water - pH 7
2. Tap water in the house - pH between 7.5 and 8
3. Tap water on the tobacco plot for irrigation - pH 8
4. Soil near the house - pH 7.5
5. Soil on the tobacco plot - pH 7.5

pH 7.5 is the maximum value for tobacco, right? Should I leave it as it is or lower it? If I lower it, which is better—pine bark or peat?
I have also already applied fertilizer to the plot... one with the composition P-19, Ca-20, S-32 and the second composition in the photo. Azote planned to apply nitrogen in the spring, before planting.

Looks like your conditions are slightly alkaline. i don't know if its so alkaline that it would benefit you to reduce the pH.
I just know that most plants absorb most nutrients best at around 6.0-6.5 pH give or take.
