From the exterior view, mineral water and tap water is virtually no distinction, even experts, From the exterior and sensory difficult to judge accurately its authenticity, in fact, once you have the right approach, mineral water and tap water is easily distinguished. 1, I really feel no smell sweet taste of mineral water, tap water has bleaching powder flavor. 2, transparent mineral water was colorless and transparent state in the sunlight, free of impurities, no turbidity; pores in a little water and sediments and suspended chief. 3, the refractive index of glass cleaner which will inject mineral water. Observe into chopstick-level index. Mineral water rich in minerals, refractive index greater than water. In other words chopstick bending phenomenon in the mineral water which has larger than in tap water. 4, the heat capacity at the same temperature conditions, mineral water absorbs heat, heat release rate is slower than the water. High-temperature mineral water in the summer season, its surface condensation droplets of water bottles, and there is no running water phenomenon. 5, higher than mineral water rich in minerals, water greater extent than their mineralization, there has been a corresponding increase in the surface tension. Will be filled with mineral water glass surface can be bulging with coins on the surface, we can find no support; This phenomenon is not tap water.
