Four samples of natural water from different sources are taken in four petri dishes in equal quantities. These are marked as A, B, C, D and kept in an oven till the entire water vaporizes. When they were taken out, it is observed that sample marked 'C' left maximum amount of residue while sample marked 'B' left negligible amount of residue. 'A' and 'D' left almost same amount of residue.
Predict the sources of A and D

AI Generated Solution

To predict the sources of samples A and D based on the given information, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Residue Left Behind**: - After evaporating the water samples, we observe that sample C left the maximum amount of residue, while sample B left negligible residue. This indicates that sample C likely contained a high concentration of dissolved solids, while sample B had very few or no dissolved solids. 2. **Identifying Sample B**: ...
