Objective 6:

1.  Acid-a compound with a taste that is sour, makes blue litmus paper red, and is a H+ ion.
2.  Neutralization-a reaction that happens between a base and an acid that yields a salt and water
3.  Indicator-a thing, like litmus, that tells the presence of a certain constituent like an acid or a base.
4.  Corrosive-eating away at something (acids are this)
5.  Hydroxide ion-an anion OH that has one oxegen and one hydrogen atom

Objective 5:

1.  They are mechanical and chemical.
http://wiki.answers.com/Q/What_are_the_two_parts_of_digestion&isLookUp=1
2.  Mechanical digestion is when you hve to do something to digest your food for yourself like chewing but chemical digestion is when a chemical called hydrochloric acid breaks down your food. http://wiki.answers.com/Q/What_is_the_difference_between_mechanical_digestion_and_chemical_digestion#ixzz16btmgJUm
3.  This means they can't do mechanical digestions so the chemical digestion has to work harder.
4.  mounth=7pH, stomach acid=1.5pH, small intestine=7

Objective 4:

1.  H+
http://wiki.answers.com/Q/What_ion_is_present_in_all_acidic_solutions
2.  The acids make hydrogen ions and the bases make hydroxide ions.
http://wiki.answers.com/Q/What_happens_when_acids_and_bases_dissolve_in_water
3.  It ends up breaking down into H+ NO3 which is an acid.
http://answers.yahoo.com/question/index?qid=20080108190009AA0Uied
4.  The pH tells you how much H+ ions that are inside of a certain acid or base.  If the pH is lower than 7 it is an acid and if it is higher it is a base.
(remembered this from the question on objective 3)
5.  The concentration of hydrogen is pretty high when the pH is low which means the pH of 3 has more hydrogen ions than the pH of 7.

Objective 3:

1.  They are if something tastes sour, if it reacts to metals or carbonates, if it turns blue litmus paper red, a pH lower than 7, and lastly if in a solution it produces hydrogen ions.
http://wiki.answers.com/Q/What_properties_distinguish_acids&alreadyAsked=1&rtitle=What_are_four_properties_of_acids&isLookUp=1
2.  They taste bitter, feel slippery, can be caustic, and turn red litmus paper blue.
http://wiki.answers.com/Q/What_are_the_properties_of_bases#ixzz16botVnjO
3.  If the paper turns red it must be an acid and if it turns it blue it must be a base.
4.  You can tell because if the food is sour it is a acid and if it is bitter it is a base.
5.  You need to wear gloves because the fertilizer will hurt your hands.  Also allows you not to wash your hans so often while doing gardening.

Objective 2:

1.  Concentration is the measurment of what amount of one thing is in another thing.  To figure this out you need to know how the solvent is compared to the solute.
http://en.wikipedia.org/wiki/Concentration
2.  Solubility is used to idenify substances because it is a characteristic property of matter.
http://wiki.answers.com/Q/Why_is_solubility_useful_in_identifying_substances#ixzz16bmbSKQR
3.  There are three types and those are tempature, pressure, and type of the solvent.
http://wiki.answers.com/Q/What_factors_affect_the_solubility_of_a_substance&isLookUp=1
4.  When the tempature is hot the solid will melt and if it is too cold it will freeze.
http://wiki.answers.com/Q/How_does_temperature_affect_the_solubility_of_a_solid
5.  It can help because of the object's characteristic property of matter.  This helps you know how easily something may be able to dissolve inside of that certain matter.

HW 10:

Objective 1: Understanding Solutions

1. What are the characteristics of solutions, colloids, and suspensions? Suspensions are a "homogeneous fluid" that has solid particals that are large.  Colloids disperse in a substance evenly and solutions have much smaller particals than either of the other two.
http://en.wikipedia.org/wiki/Solutions
http://en.wikipedia.org/wiki/Colloids
http://en.wikipedia.org/wiki/suspensions
2. What happens to the particles of a solute when a solution forms?  The particals from the solute go away and are a part of the solevent.
http://zellescienceblog.blogspot.com/
3. How do solutes affect the freezing point and boiling point of a solvent?  The boiling point of the solvent gets bigger when a solute is added because a solution has a bigger boiling point compared to a pure solvent. The freezing point gets lower also.
http://eigthscience.blogspot.com/
http://eigthscience.blogspot.com/
5. What effects do solutes have on a solvent’s freezing and boiling points?  A solute makes the boiling point bigger because a solution has a bigger boiling point compared to a pure solvent. It also makes the freezing point a lot lower.  The coligative property helps to understand the boiling point elevation.
http://en.wikipedia.org/wiki/Boiling-point_elevation4. Suppose you mix food coloring in water to make it blue. Have you made a solution or solution or a suspension? Explain.  You would make a solution because it is going throughout the water and dissolves.
