solutions and pH test

this week we took the solutions and pH test.
it was very hard, but i studies very hard so i got a 86%.
It was on titration and dilutions.
today, we turned in our reactions 1 packets and got a reactions 2 packet.
we balanced equations with cubes in a lab we did this week.
i have a lot of hw this week.
good thing the only hw for this class is pre reading the lab.

acids and bases lab

this week, we did a lab on acids and bases.
there were four stations.
the first was the one is where we saw if the solution can conduct electricity.
the second, third, and fourth one was where we saw the colors of the solutions.
we also had to answer questions about the lab.
we had to do worksheets in the green power point packet as well.
we also had to find the pH of the solutions with litmus paper.

making solutions lab

we did a lab this week with cobalt chloride.
we put a certain amount in a beaker,then filled it to 100mL with water.
then it was analyzed in the spectronic-20 machine.
we also did some more worksheets from the power point packet.
we worked on dilutions and stuff on solubility.
a new thing this week was the composition book.
we had to paste stuff in it and we get to use it on the tests!
to learn how to dilute something, click pict.

like dissolves like

this week, we worked in a blue packet for most of the week.
it was the power point packet, but there are questions in it this time.
there were stuff about solutes and solvents.
then we did a lab were we get a dropper and some dark purple liquid.
as we add more water, the liquid gets clearer.
from dark purple to purple to magenta to pink to clear.


dissolving is the process of going into solution.
for example: salt is a solute and water is the solvent.
the water dissolves the salt.

salt crystals and finals

this week, we looked at our salt crystals from the lab last week.
i got extra credit!
it is also finals week.
i'm gonna have to study a lot, even though i don't want to.
it's only tuesday.
i'm posting this blog today because i won't have time to do it later in the week.
today we are in the computer lab, because we have to study for the chemistry final.
i heard it was pretty easy, but it think i'm gonna do bad so i gots to study more!!!
i'm not gonna blog too much this week because i need more time to study.

mole stuff!

we did a lot of stuff on moles this week.
we did worksheets.
yesturday, we weighed hole punches.
hole punches were everywhere!
all around the school!
they were very colorful and pretty!
the group that got the closest to the amount given got extra credit!
i didn't get the extra credit.
we also looked at power point slides.
to learn about the mole, we watched a video with mr. olson and his friend curtis.
it was a fun video!

attractive molecules lab

this lab was about polarity of different liquids.
there was water, acetic acid, isopropanol, and kerosene.
we charged up the wand with some wool.
then we saw if it reacted.
everything reacted besides the kerosene.
the water would move left of right or in whichever opposite direction of the wand.
yesturday we read a comic and have to answer questions.
it was polar bears and penguins.
today, i am posting this blog.
that was mainly the entire week.
