Waves and Photons

Our first lecture was essentially an introduction to our unit. We learned about the wave nature of light, which i have found a very helpful link for right here:
The Wave Nature of Light

We also learned about photons and the Quantization of energy, which has a link as well:
Quantized energy and Photons

I hope these links help!

Flame test lab

In this lab, we had several different sticks soaked in different metals and elements. Each one burned a different color depending on what the metal compound consisted of. I really enjoyed this lab, for we could see how the different wavelengths affected the color of the flame. 

Study Links

Here are some links i used during this unit to help study with. I hope they help!

Titration
Acid base titrarions
Neutralization

Vinegar and Acid Lab

In this lab we were given KHP and had to determine the molarity of the NaOH solution we were given. This lab and its calculations we extremely helpful and fun when trying to get the exact results you want. It was crazy to see that just one drop could ruin your whole percent error value! 

Finding the pH of a Solution

I know it took me a lot of practice to really memorize how to find the pH of solutions, but after using these links and much practice, they have become much easier! I hope they help!

Unknown Acid Lab

In this lab, we conducted nearly the same lab as the Acid and Vinegar lab, but this time we had an unknown acid and had to titrate it. I enjoyed this lab because we got to use equipment we haven't before, such as the stirrers shown in the photo above. This lab has helped me see how the process of titration is done which is helpful for me when trying to study! 

Weak Acids

Finding the pH of weak acids are probably one the the most time consuming problems of this unit. If you follow a small set of steps, it shouldn't be as difficult.
Step one: Write down the involved species and determine the dominant species to determine who will contribute the most H+
Step two:Write the equilibrium expression.
Step three: Proceed with ICE box and solve for x.
Step four: Solve for pH or H+

Here is a link to a website that walks you through how to do an example of one of these problems. I hope that helps!
