what is a solution? | a homogenous mixture of 2 or more pure substanes. that is a soultion |
What is solubility? | the max amount of soulte that can be dissolved in a given amount of solvent @ sertien temps, this is soulbitlity. |
What is satureated? | a solition's concentration is at its solubility limit withn no additional solution can be disolved |
What is Supper satureated? | the solute concentration that exceeds normal soulbility limit under excisting conditions, highly unstable |
What is a solute? | the substance dissolved in the solvent in a solution; the minority componet in a solution |
What is a solvent? | the substance that does the dissolveing in a solution; the majority componet of a solition |
Concentration of a solution | the measure amount of solute in a given amount of solvent. It may be measured in units |
Acids / Bases | - donates hydrogen ions- acepts hydrogen ions |
Ph | turns a specific color in a solution may identify what the solution is |
List 3 observations that would indicate that substance added to a liquid is not forming a solution | a. did not disolveb. is not transparentc. can be filtered out |
How can a solute be separated from a solvent in a solution? | If it is a true solution then it cna't be filtered out |
List and describe the 3 fracters the affect solubility | a. polarityb. temp. increcec. pressure |
solution process | the attraction force of the solvent oversomes the attraction force of the solute, it breaks up and becomes clear |
describe 3 factors that can affect the rate of solution | a. tempb. grindingc. sturing |
what happens to an acid in water? | a hydrogen ion is produced |
Describe what happens to a bace in water. | hydroxide ion is produced |
How does litmus paper indicates whether a solution is an acid or base? | If it is a bace it turns blue.If it is a acid it turns red. |
what do you add to nuetralize an acid? | anti asid or put it in a bace |
