Do water and oxygen conduct electricity?
In their pure forms no.
Why is pure water a very weak electric conductor?
the number of charged particles moving around in solution is very, very small. water is undergoing self-ionization.
What ionizes water?
Water has an ionization constant of 10-14 and there is always some small degree of spontaneous ionization in liquid water, resulting from random thermal motion. At high temperatures, ionization increases. Any compound will dissociate at a sufficiently high temperature.
Is filtered water is a pure substance or heterogeneous?
from the actual sense water is not a pure substance, but if you are classifying it as either heterogenous or hoemogenous, then it is hoemogenous and not heterogenous, now heterogenous are substance that contains different forms eg liquid and solid. But water has one form (liquid)
What chemical bonds would you find in pure water?
In each water molecule each hydrogen atom forms a polar covalent bond with the hydrogen atom.
The reason pure water has a pH of 7 is that there is the same concentration of hydrogen and hydroxide ions on the self-ionization of water?
true
Do water and oxygen conduct electricity?
In their pure forms no.
Why is pure water a very weak electric conductor?
the number of charged particles moving around in solution is very, very small. water is undergoing self-ionization.
Does pure water contain only H2O molecules?
No, it contains H2O molecules along with OH- and H3O+ions from self-ionization. This is why water can still conduct some electricity.
Why does bath water conduct electricity but pure water does not?
"Bath water" or normal water, usually contain many impurities. These impurities, such as ions (especially calcium ions) help the water to conduct electricity very efficiently (just like sea water). However in pure, dH20, there are no ions and impurities. The self-ionization of water isn't enough to conduct a current. Therefore, pure water doesn't conduct current, and is actually a pretty good insulator.
Explain ionization. which forms of nuclear radiation are capable of ionizing matter?
electromagnetic
Explain ionization which forms of nuclear radiation are capable of ionizing matter?
electromagnetic
What are the 3 pure forms of carbon?
The 3 pure forms of carbon are coal graphite and diamond

What is meant by''ionization''and ''degree''of ionization?
IONIZATION:-The splitting up of a substance in to a negative and positive ions in it's aqueous solution or in fused form is known as ionization.DEGREE OF IONIZATION:-The extent to which an electrolysis can ionize in water is called it's degree of ionization.Degree of ionization of CH3COOH = 4/1000
Do the elements form anion have high or loe ionization energy?
low ionization energy
The abbreviation Kw represents the what?
The ionization constant of water at 250C, its value is 1x10-14 A: ion-product constant of water.
