Analysis of Water Sample
Freezing Point
Water usually freezes at 0॰C, but this sample of water freezes at about -2॰C. This indicates that the sample might be impure. When water is pure, its freezing point is not lower than 0॰C. The presence of impurities like salts, sugars, or other substances will lower the freezing point of water. This phenomenon is known as freezing point depression.
Boiling Point
Water usually boils at 100॰C, but this sample of water boils at about 101॰C. This indicates that the sample might be impure. When water is pure, its boiling point is not higher than 100॰C. The presence of impurities like dissolved minerals, gases, or other substances will increase the boiling point of water. This phenomenon is known as boiling point elevation.
Conclusion
Based on the above analysis, it can be concluded that the sample of water is impure. The presence of impurities has lowered its freezing point and raised its boiling point. To determine the exact nature of impurities, further tests would be required. For example, a conductivity test could be conducted to determine the presence of dissolved ions in the water sample.
