Ms.Kozoriz wasn't in class that day, and so we had a sub, and it was Mrs.Karras(I think that was her). And she said we had to finished the lab, An Analogy for an Equilibrium Reaction, and also in the yellow worksheet that Ms.Kozoriz gave us, Lesson 3, we have to do questions 4-8 oAnd pretty much that happen in class. So my scribe is very short but yeah.

Next scribe is Albert

I DIDN'T KNOW

Hello.I didn't realize I was the scribe for today but oh wells.
So anyways what we did in class today was we hand in our worksheet that was due today the "Neutralization Problems."

Next what we did in class was a Lab. The Lab was called, "Titration Lab."

• What we did was we measured out 1.0 mL of distilled water into a 10 mL graduated cylinder. Must repeat 3 times to get an accurate result.
• After that was done, we had to measure out 5 mL of distilled water into the graduated cylinder and then place that amount into a 50 mL beaker. And after we added a DROP of PHENOLPHTHALEIN INDICATOR. And swirled it a bit.
• Next we took H2SO4 (SULFURIC ACID) and added 20 DROPS into the beaker and then transfered that solution into the graduated cylinder to measure the volume. Then we placed it back into the beaker.
• Next we then took NaOH (SODIUM HYDROXIDE) and had to COUNT the NUMBER OF DROPS that made the solution in the beaker to a permant pink color.
• Then we place that solution back in the graduated cylinder and measure the volume of that solution.
• After that was done, we cleaned out the equipment and did that lab again 2 more times so we can get an accurate result
• And after we cleaned out the equipment and cleaned up.

And that was pretty much what we did in class today. No notes, no homework (unless you didn't finish the other assignments.), and that was all. =D

So the next scribe for tomorrow will be : KAYLA =D
