Question

What is the difference between heavy water and ordinary water?​

Answer 1

Answer:

In ordinary water, each hydrogen atom has just a single proton in its nucleus. In heavy water, each hydrogen atom is indeed heavier, with a neutron as well as a proton in its nucleus. This isotope of hydrogen is called deuterium, and heavy water's more scientific name is deuterium oxide, abbreviated as D20.

Answer 2

The main difference between Heavy water and normal water is their chemical composition.

Normal water: It is the general water that we use to drink everyday and will also be used for various purposes. Its chemical formula is $H_2O$. So, normal water has two Hydrogen atoms and one Oxygen atom combines to make a water molecule. It is not harmful to consume.

Heavy Water: In the other hand heavy water is mostly look similar to the normal water but instead of two Hydrogen atoms, it has two Deuterium atoms($D_2O$). Deuterium atom is very much similar to Hydrogen atom but has an extra neutron which makes it heavier. And Heavy water is dangerous if consumed. Due to its heaviness, our human body will not able to mix it with the blood stream and causes health issues.

NOTE: Please refer to the table attached to get more differences between heavy water a normal water.
