What else can I help you with?
What would happen to a saturated solution if cooled in the refrigerator?
If it is saturated with a solid solute, you would expect some of the solid to precipitate out - as long as the solid could find a surface to nucleate on. If it is saturated with a gas, you would expect more gas to dissolve into it as long as it was still in contact with the saturating gas in the gas phase.
Would you expect the pH of an solution of soap to be 4 or 9?
9
Would you expect a concetrated solution of sugar in water to boil at 100?
The solute in a solution modify the boiling point of water.
Where can contact solution be purchased from?
Contact solution can be purchased at most departmental stores and pharmacies. Some examples of these stores would be Walgreens, Target and CVS pharmacy.
Which would you expect to have a greater influence on the effect of a solution in natural water concentration or solubility?
The concentration; to prepare a solution the compound must have a solubility.
What values of pH would you expect for a sodium chloride?
Water solution of sodium chloride is neutral.
What values of pH would you expect for sodium chloride?
A water solution of sodium chloride is neutral.
If the pH of a solution is 6 would you expect to find more or fewer hydrogen ions than a solution with a pH of 3?
You would expect to find fewer hydrogen ions in the solution with a pH of 6 compared to a solution with a pH of 3. pH is a measure of the concentration of hydrogen ions in a solution, so as the pH value increases, the concentration of hydrogen ions decreases.
Phenolphthalein solution is used as an indicator of acids and bases. If added to an ammonia-based solution of window cleaner we would expect the solution to turn?
Phenolphthalein will turn pink or magenta in basic solutions and remain colorless in acidic solutions. Therefore, if added to an ammonia-based solution of window cleaner, which is basic, we would expect the solution to turn pink or magenta.
What values of a pH would you expect for sodium chloride common salt?
A water solution of sodium chloride is neutral.
Would you expect iodine to displace bromine form a solution of potassium bromide?
No. However, bromine would displace iodine in potassium iodide.
Which would you expect to have the greatest amount of friction?
I would expect a rough surface to have the greatest amount of friction due to the increased contact points between the surfaces, resulting in a higher resistance to motion. Smooth surfaces typically have less friction due to reduced contact points.
