 solute | a substance that dissolves in a solvent to form a solution |
| salt, citric acid, baking soda | examples of solutes |
| water | the universal solvent, because so many solutes are able to dissolve in it |
| soluble | being capable of being dissolved |
| saturated solution | a solution in which as much solute as possible has been dissolved in the solvent |
| a solution is saturated when... | no more solute will dissolve and the solid begins to collect on the sides or at the bottom |
| solvent | a substance that dissolves a solute to form a solution |
| volume | the amount of space that an object takes up or occupies |
| describe what happened to the volume of the citric acid and water solution as more citric acid dissolved | the water level went up or increased because the citric acid took up space as it dissolved |
| mass | the amount of matter in an object |
| describe what happened to the mass of the salt and water solution as more salt dissolved in the solution | there was more matter in the solution as the salt dissolved, and this made the mass go up |
| describe how you use a balance and gram pieces to determine the mass of the citric acid dissolved in your solution | On one side we placed fresh water and on the other side the citric acid solution. We added gram pieces to the fresh water until it balanced. |
| shaking, stirring, letting it sit, heat | factors from our lab that effect the solubility of the solutes we used |
| as you travel higher above sea level, there is less air pushing on you because... | the air has less molecules higher in the atmosphere |
| nitrogen and oxygen | two gases that are dissolved in our blood when the air we inhale enters our lungs |
| decompression sickness (the bends) | occurs when pressure is decreased or dropped very quickly and nitrogen bubbles are released from the blood stream |
| upset stomach and lack of muscle control | symptoms of decompression sickness |
| facts/properties of citric acid | white, powdery grains; found naturally or artificially added; harmful to mucous membranes and the skin; sour taste |
| sweet, sour, salty, bitter | the tastes that our tongue can detect |
