Explanation:
Ph=-log[H+]
to find the h+ is the antilogarithm of the Ph.
Which is 10 raised to the power - Ph.
In a solid, atoms are packed very closely together, almost like an organized grid. They vibrate, and rub against each other, but stay in the same place.
In a liquid, atoms are farther apart, and slide around each other, which is why if you pour water on the ground, it won't stay in any specific shape unless it is in a container. However it does stay together. Gas on the other hand is very spread out with a lot of space in between the individual atoms. All the space allows gases to expand and contract. Gas atoms bounce around, and will not hold a form or stay together.
Explanation:
Oxidation reduction reactions are the reactions in which one specie oxidizes and other reduces.
For example,
This is a oxidation reduction reaction because sodium in elemental state ( 0 oxidation state) oxidizes to Na⁺ in NaCl. Also H⁺ in HCl reduces to H° in H₂.
Elements are present in 0 oxidation state and either it is formed or consumed, its oxidation state has to be changed for a chemical reaction to occur. Hence, it is true.
