electrical conductivity experiment using saltwater

electrical-condustivity-using-salt-water-experiments

Electrical conductivity in water refers to its ability to conduct an electric current. The presence of dissolved ions, such as salts, minerals, and other charged particles, allows water to conduct electricity. When salt is added to water, it increases the concentration of ions, leading to higher electrical conductivity. Here’s how electrical conductivity in water with … Read more

distillation of water working model and explanation

distillation of water working model :

What is distillation of water? Distillation of water is the process works because the steam that is produced when the water boils is pure, since it has left any impurities behind in the large pot. When the steam condenses using cold water, it forms pure water droplets that are free from impurities. By collecting these … Read more
