Understanding Solutions
a well-mixed mixture that contains a solvent and at least one solute.
What is a Solution?
what is the difference in a Dilute Solution and a Concentrated Solution?
what is a dilute solution is a mixture that has a little solute dissolved while a concentrated dilute that has a lot of solute dissolved?
What is an Acid?
an atom of hydrogen that has lost its electron
What is Hydrogen Ion?
the process that breaks down the complex molecules of food into smaller molecules
what is Digestion?
examples of common solutions
Air, Soda Water, Antifreeze, Dental filling, Ocean Water, Brass
a measure of how much solute can be dissolved in a solvent at a given temperature.
What is Solubility?
"eat away"
What is Corrosive?
a negative ion made of oxygen and hydrogen
What is a Hydroxide Ion?
a physical process in which large pieces of food are torn into smaller pieces but not changed into different compounds, while a chemical process that the food changes into different molecules
what is the difference between Mechanical and Chemical Digestion?
a mixture that contains small, undissolved particles that do not settle out
What is a Colloid?
factors that effect solubility are _______________.
What is pressure, the type of solvent, and temperature.
litmus paper is an example of _______
What is an Indicator?
(a base is a substance that produces hydroxide ions)
Is this statement true of false?
What is true?
pH scale = 7
what is the mouth?
a mixture in which particles can be seen and easily separated by settling or filtration
What is a Suspension?
Solubility increases as the Temperature?
What is increases?
a substance that tastes bitter, feels slippery, and turns red litmus paper blue.
What is a Base?
a range of value from 0 - 14
what is a pH scale?
pH scale = 2
what is the Stomach?
what a solution forms, particles of the _________ leave each other and become surrounded by particles of the ________.
What is a Solute, Solvent
has more dissolved solute than is predicted
what is Supersaturated Solution
Acids and bases have many uses around
What is " the home and other industry's"
a low pH scale tells you that the concentration of hydrogen ions are high. so what does a high pH scale tell you?
what is that the concentration of hydrogen ions are low?
pH scale = 8
what is the Small intestine?
