- compound is the most soluble at 20 degress C
- sodium nitrate
- precipitate
- the excess solute that settles out
- What is the reaction of hydrogen in the down position with a flaming splint?
- pop, small explosion
- What temperature is needed to exactly dissolve 60g of potassium nitrate in 100 cm cubed of water?
- 39 degrees C
- unsaturated
- a solution that contains less solute than it can possibly hold at a given temperature.
- 90 grams of potassium nitrate are dissolved in 100 cm cubed at 25 degrees C. The solution is now heated to 100 degrees C. Does the concentration change?
- Yes, more can be dissolved now.
- What is the solubility of sodium chloride in 100 cm cubed at 50 degrees C?
- 37g per 100 cm cubed
- At what temperature are the solubilities of ammonium chloride and sodium chloride the same?
- about 20 degrees C
- dilute
- a solution in which there is little solutive dissolved in a solvent
- saturated
- a solution that contains all the solute it can possibly hold at a given temperature
- solute
- the substance that is dissolved
- solvent
- the dissolving medium
- What is the density of hydrogen, carbon dioxide, and ammonia?
- less, more, less
- 100 g of sodium nitrate are added to 100 cm cubed of water at 25 degrees C. What is the concentration at 25 degrees C?
- 90 g per 100 cm cubed
- How is hydrogen produced?
- dissolving magnesium in sulfuric acid
- List the most important source of error for each experiment in this chapter.
- 4.3- splattering, not dry 4.4- didn't stir while heating, only used 5g of solid 4.6- miscounted pinches 4.8- not waiting 60 seconds, touching sides with wood splint 4.111- not heating long enough
- concentrated
- a solution in which a lot of solute is dissolved in a solvent
- How much sodium nitrate would you have to add to 100 cm cubed of water to produce a saturated solution?
- 79 grams
- Explain why water column in the test tube after removing the stopper.
- ammonia dissolved so quickly that it left an empty space that the water filled. there was an air pressure imbalance because there was no air in the test tube and then the air outside the tube pushed down on the water sending it into the tube.
- tincture
- a solution in which alcohol is the solvent
- Solution
- a homogeneous mixture in which one substance is dissolved in another substance
- compound least soluble at 20 degrees C
- potassium nitrate
- concentration
- the amount of solute dissolved in a certain amount of solvent
- What is the solubility of potassium nitrate at 60 degrees C?
- about 108 grams per 100 cm cubed of water
- 50 g of sodium chloride are added to 100 cm cubed of water at 100 degrees C. how much will dissolve at this temperature?
- 40 grams
- 35g of substance X will dissolve in 65 cm cubed of water. How much will dissolve in 100 cm cubed?
- 54 grams
- How much sodium chloride will dissolve in 25 cm cubed of water at 100 degrees C?
- 10 grams per 25 cm cubed
- solubility
- a measure of how much of that solute can be dissolved in a given amount of solvent under certain conditions
- Why does the temperature only go up to 100 degress C.
- water boils at that temperature
- aqueous
- solutions in which the solvent is water
- homogenous
- that solute molecules are evenly spread among solvent molecules
