what is the answer to the question displayed in the end of the video is it purple?

[@waleedomari8042]

Yes it is purple

[@fatimaalamien8786]

What’s the answer ? Is it medium?

[@waleedomari8042]

It’s purple, so High co2 concentration The plant is in direct sunlight, meaning photosyntheses will occur. Photosynthesis uses co2, so co2 will be taken into the plant. Thill will lessen the co2 concentration and therefore the hydrogen carbonate indicator will turn purple
