Does absorbance increase or decrease as the solution concentration of the substance increase?
Absorbance typically increases as the solution concentration of a substance increases. This is because absorbance is directly proportional to the concentration of the absorbing species, as described by the Beer-Lambert Law. As more molecules of the substance are present in the solution, more light is absorbed, leading to higher absorbance readings.
What else can I help you with?
What name is given to substance the decrease the concentartion of hydrogen ions in solution?
A substance that decreases the concentration of hydrogen ions in a solution is called a base or alkaline substance. It helps increase the pH of the solution, making it less acidic.
Will the pH increase decrease or remain the same if the concentration of weak bases increases?
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.
When citric acid is added will the pH increase or decrease?
When citric acid is added, or any acid for that matter, the pH of a substance will decrease. This is because since acids have a low pH they will decrease the pH of other substances when added to it.
What increase absorbance of phenol in ethanol?
Possible factors that can increase the absorbance of phenol in ethanol are: increasing the concentration of phenol in the solution, using a higher path length cuvette for measurement, and selecting a wavelength for measurement where phenol has a higher molar absorptivity coefficient.
What happens to the hydronium ion concentration if you increase the hydroxide ion concentration?
If you increase the hydroxide ion concentration, the equilibrium will shift towards the formation of more water molecules. This will result in a decrease in the hydronium ion concentration.
If a solution is diluted will the absorbance decrease or increase?
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.
Can the concentration of a substance change if it is an aqueous solution?
Yes. An aqueous solution means that at least one solute is dissolved in water. You can increase the concentration by adding more solute, or you can decrease the concentration by adding more water.
How can you change concentration?
To increase the concentration of a solution, you can decrease the amount of solvent by boiling off, or by evaporation, or you can simply add more solute. Conversely, to decrease the concentration, you can add more solvent.

How do you change the concentration of a substance?
Add more or remove some of the substance from the mixture, or add or remove some other substance from the mixture. Removal is usually more difficult, with heating (distillation or boiling off) or filtration (of a solid) being among the most direct methods.
When citric acid is added will the pH increase or decrease?
When citric acid is added, or any acid for that matter, the pH of a substance will decrease. This is because since acids have a low pH they will decrease the pH of other substances when added to it.
How does temperature affect the volume of substance?
An increase in temperature will cause an increase in volume, while a decrease in temperature will cause a decrease in volume.
What increase absorbance of phenol in ethanol?
Possible factors that can increase the absorbance of phenol in ethanol are: increasing the concentration of phenol in the solution, using a higher path length cuvette for measurement, and selecting a wavelength for measurement where phenol has a higher molar absorptivity coefficient.
What would you do to increase or decrease the concentration of the nutrient solution?
The amount of water you add.
If an acid is added to a solution does the H plus concentration increase or decrease?
It increases.
Does a substance density increase or decrease when it has a high amount of kinetic energy?
No.
