Dry Ice in Universal Indicator

The effect of carbon dioxide on the pH level of water is demonstrated by dropping a couple chunks of dry ice into a column of universal indicator. The indicators in the two columns are initially set up to be basic, so that we may see the effect of the dry ice more clearly. When a few dropper-fulls HCl 1M is added, the color changes and persists as orange; when NaOH 1M is added, the color momentarily changes back to purple, but then quickly goes back to yellow as more of the dry ice sublimates.
Always wear proper PPE when working with chemicals!

Sir air seeing can I do in telugu sir plz

How can adding carbon dioxide to water decrease its pH level while increasing its acidity? Or did i misunderstand that

[@NatSciDemos]

Acids have pH values less than 7; the lower the pH, the stronger the acidity.

Makes a lot of mistake when he demonstrates indicator. Calculate the enough material and measure its mass!
