States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
Write the autoprotolysis equation for water(chemical equation) and give the value for the equilibrium constant.
Water molecules are Amphoteric in nature and can act as both acid and base. Water molecule acting as a base will accept Proton and form hydronium ion and water molecule acting as acid will donate proton and form Hydroxide ion.
This process is called as autoprotolysis of water.
The hydronium ion is a strong acid and hydroxide ion is a strong base in water and will react to produce water again. thus an equilibrium is setup between them.
Chemical equation for autoprotolysis of water is:
