Post 2 Acid and Base

Getting for the first quiz of this unit.
Acids [H+] and bases [OH-] together produce a salt and water. Acids produce conjugate bases and bases produces conjugate acids. These can then change through reactions.

When converting H+ to OH- use the equation H+ = Kw/ OH- in which Kw = 1.0 x 10^-14 and this equation can be used with OH- interchangeably

H+ to pH and OH- to pOH uses -log and going from pH to pOH would subtract 14.

We did another lab that involved the titration of vitamin c and iodine, which produced a clear color, and starch, which turned the solution blue to determine the concentration of vitamin c within different juices. Unsurprisingly, the grapefruit juice contained the most.

Our latest unit includes both stoichiometry and molarity in calculations that, just like stoichiometry, convert volume (ml, L) using molarity (mol/L) into mols which are then converted into the new unit.
Here's a video that goes over it. youtube
Here's another website that goes over the step by step process of  calculating molarity using stoichiometry. yeahchemistry

We have recently finished gathering the data for the murder investigation lab which involved double replacement chemical reactions, determining which reactions produced solids which when then used to determine that the mystery poison was silver carbonate. Here's a link to the lab. murder mystery lab

We discovered that the culprit was Mr.Green.

We did a lab that went over the concentration of stocks which involved diluting a stock of food colored water until the coloring had disappeared. Overall, it was a fun simple lab that got us into the new unit.
