which of the following best describes a solution that contains a buffer?
sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.
Is a solution a physical or chemical change?
A solution is not a change; a solution is represented by a solute dissolved in a solvent; but dissolving (without chemical reaction) is a physical process.
How does the rate of temperature change depend on the temperature difference between the two beakers?
to tell you the truth this is a hard question so i really cant answer it sorry who ever was looking for this answer.
What will be the color change of crystal violet at different pH?
Crystal violet is used in Gram's method of bacteria classification. At a pH of 1.0, the solution turns green, and when in a strongly acidic solution, it turns yellow.
What is the overall energy change that occurs when a solution forms?
heat of solution
What is the process responsible for the change in mass of the dialysis tubing in the beakers?
Diffusion
Which term describes a state of matter that has a definite volume but no definite shape?
Liquids because when they are put into different beakers their shapes might change but their volume will always be the same.
How do you determine the concentration of ascorbic acid in unknown sample?
first measure the volume of the sample solution needed to change the blue color of the DCPIP solution into colourless. then, weigh the mass of the sample solution. finally calculate the concentration by using the formula: volume required t change the color of DCPIP solution (dm) per mass of the sample solution (g)
Why does salt separated from a saltwater solution look different that the salt that dissolved in the water?

Actually, change in things is a basic nature that what people required. Many people want change it's different thing that whether it is likable or not.
Can bases be classified with an indicator?
Yes. There are many different types of indicators that change colors at different levels of pH. While it will depend on you concentration of base. You can use it indicate if a solution is basic, and narrow down the actual species in solution.

What is the colour change in glucose when Benedict's solution is added to it and is heated?
Because starch and glucose are two different tests and there are different reactions that can occur in the process of these tests.

it is a chemical change
Can anything change a solution?
Adding more solute or more solvent can change a solution.
