Cu to the Lai

Miss Cule [Cu-lai] has always been there for her students, whether the times were good or bad, which is why anyone who will ever have her class (whether it's chemistry or not) will have such a great time and will always feel like asking questions is really easy.


Something that I've learned in my chemistry classes this year is the Kc formula, how the pickles go over the relish, because the products always go over the reactants.


My only advice to the new students would to one, always be confident (it's gotten me mistaken a lot of times!) and two, to always ask your questions to participate in class and three, to always be there! You don't want to miss out on a class with Miss Cool! :D


All you need to be is confident, a hard-worker and say...

This is me signing off for the last time,

pH, pOH and Logarithms!

It's a good thing I've had Logs in math before this unit came along!
I'll start by giving you tricks for the calculations of pH and pOH:

Let's go over the basics, shall we?

Overview of what the Voicethread on this lesson explained to us:

But what if we're given a question like this:

We need to remember the basic Log function and the manipulations we can do to it!

Here's how to solve the question (notice the color-codes)!

The Basics of Kc

This blog post will simply point out how the Kc can be found, the easiest way I can.


So, let's start off with an equilibrium equation:

Now, if you have problems remembering which part of the equation goes where, you can find yourself an acronym or just stick with mine: 

Ketchup, Pickles and Relish.

Just remember that K = P/R, and that should do the trick. Let's see it done for real:

Now that we know the non-culinary format, we can go ahead and solve this puppy.

And there you have it! Hopefully this has helped you better understand the K constant. :)
