Most of my cites are from my notes:
Objective 1:
1. solution-will-mixed/ contains two things: solute and solvent
colloid- has large particles that "settle- out" slowly
suspension- particles mix briefly if at all
2. The solute always mixes into the solvent
3. They lower the freezing point and higher the boiling point
4. a solution because you add a solute(food color) into the solvent (water)
5. freezing point lowers, boinging point higher
Objective 3:
1. Tastes sour, corrosive, litmus paper changes to "red", hydrogen ions
2. Feels slippery, litmus paper changes "blue", hydroxide ions, ends in "ide"
3. bases are usually blue and acids are usually red.
4. if the food is sour
5. acids or bases can burn you(chemical burn)
Objective 4:
1.Hydrogen ions
2. Hydroxide/ Hydrogen (H^+, OH^-)
3. OH^+
4. if it is an acid or a base. How strong it is
5. Because aids are in your stomach to break down foods
Objective 5:
1. Stomach and small intestine
2.stomach is full of acid and breaks down your food. Small intestine digests fats, proteins, and carbohydrates and it mixes foods.
3. It would take longer because the food bits would be bigger.
4. Mouth is acidic... tested in class. Stomach is acidic because it has acids to break down foods. Small intestine is acidic also to break food down and mix it.
5. acids break down and acids/ bases help digest food.
Objective 6:
Acid: 0-6 on the pH scale.
Neutralization: act of making things neutral
Indicator: chemical detector for protons in acid/base titrations
Corrosive: disintegration into atoms
Hydroxide ions: bases when OH^- is formed , the water loses/gains electrons.
