The amount of water you add.
If the concentration of weak bases increases, the pH of the solution will increase. Weak bases accept protons in solution, leading to a decrease in hydrogen ion concentration and an increase in hydroxide ion concentration, which in turn raises the pH.
It increases.
The molarity of a solution can be changed by adding more solute to increase the concentration or by adding more solvent to decrease the concentration.
To increase the molarity of a solution, you can add more solute to the solvent or decrease the volume of the solvent. This will increase the concentration of the solution, resulting in a higher molarity.
When more solvent is added to a solution to decrease its concentration, it is called dilution. Dilution involves reducing the concentration of solute particles within the solution by adding more solvent to increase the total volume.
You could adjust the amount of nutrient added to the solution, dilute the solution with water, or add more water to increase the volume of the solution, which would lower the concentration of nutrients.
When an acid is added to a solution of an alkali, the pH of the solution will decrease. This is because the acid will increase the concentration of hydrogen ions, leading to a more acidic solution.
AN increase n pressure, an increase in gas concentration in the solution
An acid increase the hydrogen ion concentration in a solution.
You can decrease the concentration of a solution by diluting it with a solvent, such as water. Another way is by adding more solvent to the solution to increase its total volume, which effectively lowers the concentration of the solute in the solution.
If a solution is diluted, the absorbance will generally decrease. This is because the concentration of the absorbing species is lower in the diluted solution, resulting in fewer molecules to interact with the incident light and therefore lower absorbance.
