A possible explanation for this color change could be the acid present in the Snail slime has brought the color change.
Explanation:
- Snails are Gastropod molluscs.
- They secrete a mucus like watery slime to adhere to the surface .
- Snails also use their slime as a defense.
- Chemical analysis of snail slime suggested that it contains hyaluronic acid and glycolic acid along with other components.
- Thus we can state that snail slime is acidic in nature.
- In the given question it is stated that the blue solution turns yellow on adding a weak acid.
- So when the color of water changed from blue to yellow after 30 minutes, we can assume that the colour change was caused due to the slime secreted by Aquatic snail that was introduced into the tube.
As you can see in the picture presented below, the three classes of water have distinctive traits.
Pure substances contain only one element, they are not mixtures of different things.
The homogeneous mixtures have multiple elements, but they are so well blended together that you can't easily observe or separate them.
In heterogeneous mixtures, we can easily differentiate between different elements of the mixture.
