Question

Understanding fluid and electrolyte or acid-base balance can be particularly difficult.

Share with the class your preferred method of learning and understanding these complex processes.

Share any links to outside sources that you have found helpful.

Next, create a challenge question for your classmates to see if they can respond based on the method or resources you've shared.

Answer 1

To balance a reaction, we can use the 'n factor' method.

Steps-

1- Find the n factor of the reactant sides

2- Cross multiply with the reactant.

3- Balance no. of oxygens and hydrogen in both reactant and product side by using H2O.

4- Balance charge on both sides.

(Note- Do Step 3 and 4 together.)

You can refer to books of "Cengage- physical chemistry".

Question- MnO4 ^ (-1) + C2O4 ^ (2-)  ------------> Mn^ (+2) + CO2

Sol-   Step 1- n=5 n=2

Step 2- 2MnO4 ^ (-1) + 5C2O4 ^ (2-)  ------------> Mn^ (+2) + CO2 (CROSS MULTIPLY)

Step- 3 and 4 - 16H^ (+) + 2MnO4 ^ (-1) + 5C2O4 ^ (2-)  ------------> 2Mn^ (+2) + 10CO2 + 8H2O.

which is the requied equation.

Que- Balance the following reaction.

K2Cr2O7 + 14HCl ---------> KCl + CrCl3 + Cl2
