An unknown substance is added to a solution and the pH increases The substance is best described as what?
The unknown substance would have to be a basic solution. At least more basic than the initial solution. The pH scale ranges from 0,Most acidic, to 14, Most Basic. If the pH of your solution increases when the unknown substance is added, then it would lead you to believe that the added substance is of a basic nature.
What do the particles of sugar do when added to tea?
because of the substance causing it to do the solution
What best describes a buffer?
A buffer is a substance in a solution that releases and captures hydrogen ions, keeping the pH the same.Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not changeA buffer resists change in pH by accepting hydrogen ions when acids are added to the solution and donating hydrogen ions when bases are added.
Is it a chemical reaction when one substance is added to another substance and it becomes warmer?
Thousand of thousands chemicals can be combined by chemical reactions.
What is titrant and analyte?
Analyte: the substance to be analyzed by titration. Titrant: the substance (with a known concentration) added to the analyte solution to perform a titration.
What will happen if a highly concentrated substance is added to a solution?
It will gradually diffuse until it reaches equilibrium.
What substance forms a solution in water with a PH of 7?
Nothing because water is the only substance which has a PH of 7. Anything added to the water would change the PH unless you added pure water to it.
What causes the equilibrium to shift when a cooled saturated potassium nitrate solution is added to water?
When a cooled saturated potassium nitrate solution is added to water, the concentration of the potassium nitrate decreases making it less likely that he substance will precipitate out of solution.
What is a substance that neutralizes smell amounts of acids or bases added to a solution?
It's called a buffer solution. It's used to help maintain the same pH.
What is the dark colored substance that is formed when lead II acetate is added to the test solution?
Lead (2) Sulfide
What happens when onel material forms a solutions with another material?
a solute and solvent are added together to form a solution. the solvent is the liquid and the solute is the substance that is dissolved by the solvent and together, they form a solution! yay!!
What is the substance that neutralizes small amounts of acid or bases added to a solution?
Acids are added to neutralize base and inverse; a buffer only stabilizes the pH.
