The correct answer is the second option; sodium (Na) and potassium (K.)
Both sodium and potassium have the same number of valence electrons.
If it's saturated, it means that you have reached the maximum of KNO3 that can be dissolved in tour solution. Hence, if you add more solid KNO3, if won't dissolved, and will just fall at the bottom; as a result, the concentration in dissolved KNO3 will remain the same.

12.Neutralization
Answer:The four main factors that affect the rate of chemical reactions are temperature, concentration, surface area, and the presence of a catalyst. cause the particles (atoms or molecules) of the reactants to move more quickly so that they collide with each other more frequently and with more energy.
Explanation: lol sorry for putting 4 factors
