Homework 10

Objective 1
1. A solution is a mixture of two things, and one is solute and the other solvent, a colloid is two things mixed together but water separate out, example milk. A suspension is when components will not settle out so they will not stay together, example oil and water. http://chemistry.about.com/od/lecturenotesl3/a/colloids.htm
2. They dissolve into solvent.
3. They make the freezing point lower and boiling point higher, example washer fluid in your car and salt on an ice road.
4. You have made a suspension because the water and food coloring will mix but then level out again.
5. The solute might either raise the boiling point or lower the freezing point.
Objective 2
1. It is measured on how much of one substance is mixed with another.http://en.wikipedia.org/wiki/Concentration       I pretty much did a direct qoute
2. It is important so you will know how well it mixes so you can identify how much solute is added to the solvent.
3. If it is a covalent or ionic bond.
4. Some substances will not mix if he solvent is too cold or too hot.
5. This will help because if you know what things will bond and what will not bond, you can rule out certain
substances.
Objective 3
1. Conducts electricity, sour tasting, reacts with base to neutralizes its properties, reacts with active metals to liberate hydrogen gas (H2)
2. Conducts electricity, Bitter tasting, reacts with acids to neutralizes its properties, feels slippery to skin. BOTH ONE AND TWO ARE FROM the first thing that comes up when you search four propeties of acids, url would not copy
3.Litmus paper will change colors depending on an acid or base and if it is a 1-6 it is an acid 7 is neutral  and 8-14 is a base
4.  If the food has an ingredient ending in "ic"
5. The acid in the fertilizer can burn your hands or react with your skin and give you a harmful rash.
Objective 4
1. H3O+  are found in acids
2. in water acids and bases form positive ions
3. It would be H+NO3    http://answers.yahoo.com/question/index?qid=20090430035238AAt53le
4. How strong the acid or base is.
5. The acid with a Ph of 6 would have less H+ ions than and acid with a Ph with 3
Objective 6
Acid       Taste sour

·         Corrosive- react with medals and corrodes it

·         Changes Litmus paper to “red”

·         Produce Hydrogen ions H⁺

·         Acid will end in “ic” example, Sulfuric,  acetic

·         Ph measured 1-6

      Neutralization- when you combine the opposite a substance with the substance there for equalizing the substances
      indicator- substance or object that tells if something is happening or not
      corrosive- when an object is able to be broken down releasing hydrogen and the object goes away or folds up 
      Hydroxide ion- is a negatively charged particle  that is found in bases
