Here's an easy way to remember them, attached: </span>
Balancing redox reactions:
Oxygen should be balanced by adding
as needed, while hydrogen should be balanced by adding
.
What is a redox reaction?
Redox reactions, also known as oxidation-reduction reactions, involve the simultaneous oxidation and reduction of two different reactants.
The Half-Equation Method is one technique used to balance redox processes. The equation is divided into two half-equations using this technique: one for oxidation and one for reduction.
By changing the coefficients and adding
,
, and
in that order, each reaction is brought into equilibrium:
- By putting the right number of water (
) molecules on the other side of the equation, the oxygen atoms are brought into balance. - By adding
ions to the opposing side of the equation, one can balance the hydrogen atoms (including those added in step 2 to balance the oxygen atom). - Total the fees for each side. Add enough electrons (
) to the more positive side to make them equal. (As a general rule,
and
are nearly always on the same side.) - The
on either side must be made equal; if not, they must be multiplied by the lowest common multiple (LCM) in order to make them equal. - One balanced equation is created by adding the two half-equations and canceling out the electrons. Additionally, common terms should be eliminated.
- Now that the equation has been verified, it can be balanced.

<h3>Answer:</h3>
Correct Option-A (Ability to burn skin)
<h3>Explanation:</h3>
When skin tissues are exposed to Acids or Bases a chemical burn occurs as both of these substances are corrosive in nature. These burns occur without providing any heat, results from a very fast reaction, are extremely painful and causes damage to structures present under skin.
Option-B is incorrect because Acids taste sour, while, Bases taste bitter.
Option-C is incorrect because pH of Acids is less than 7 while, pH of Bases is greater than 7.
The answer is 14.
Hope this helps
