AP Chemistry
Unit 7 – Equilibrium
Topic 7.12
Why is the common ion replaced with the molarity already present (ex. 3M of a salt) instead of 3 +/- nx (n represents the ratio multiplier)?
To avoid a complicated quadratic when solving.
Because the difference is so small as to be negligible.
To save time and take advantage of the 5% approximation and drastic simplification.
All of the above.
