One
of the first few times we used math in chemistry was to convert things. We
started with converting Joules to Kilojoules and cal to Cal, vice versa. Then
we moved on to moles which was almost the same process; you put the
measurements with the same units one on top and the other on the bottom so when
you cross multiply to solve the same units would cancel each other out. Now
we're doing solutions and while learning about solutions I learned there is a
lot of math in chemistry. Mostly just multiplying and adding but there’s still a
lot of math involved in the process. We've used the most math in figuring out
the concentration of a solution or how to dilute a solution or find how many
grams/milliliters of the substance you need. But before I get into all of that
there are some things you should know. The definition of a solution is a
mixture of two or more substances that consist of ions. Solvation is the
process of surrounding solute particles with solvent particle; basically
putting what you want to dissolve in water. Along with this definition there
are factors that can affect it. To speed the solvation you can agitate the
particles by shaking or stirring them, the particles size can also affect it
because of the surface area, and also raising the temperature can speed up the
reaction. The difference between Concentrated Solution and a Diluted Solution
is the concentrate has more solute and the dilute has less solute, To see this
we made a solution and then diluted it in a lab and for a practical on a quiz.
For the lab we first had to get the concentration we would have and we were supposed
to be trying to solve for the amount in gram of the substance we need to make
that concentration in the solution. After that we did the math and found the
number of grams. So we filled the flask half way with water, pour the substance
in, capped the top and shook it. When we could see there were no more particles
left we filled the rest of the flask you until the marked white line. This was
all just for the concentrated solution. To make the diluted solution we got the
concentration for our teacher then had to figure out how many ml if the
concentrated solution we would need to get the new concentration. After we did
the math we measured out the amount of mL we needed in a graduated cylinder,
filled the flask half way with water, poured the concentrated solution form the
graduated cylinder, capped it and shook it .The way we could tell it was
diluted was because the dilute was always lighter that the concentrate.
