2. Please complete the SIDE 1 –
Stiochiometry 5a – Acid Base Reactions new.pdf worksheet with using the posted video below.
This is a lesson in writing Net Ion Acid/Base Reactions!
*Remember that soluble salts (aq) were never written together in NET ION EQUATIONS while the precipitate (s) are because they do exist in a crystal together. In Acid/Base the “soluble ” compound is the “Strong” Acid or Base because they completely dissociate just like soluble salts, however weak acids and bases are NOT completely dissociated thus must be written together. WATER IS A NEVER Written dissociated because they barely dissociate!!!

Okay i made an error on the last net ion reaction. The product of NH3 and H3O+ is NH4+ and water (H2O)! Sorry about that! I was trying to illustrate the reaction between a Strong Acid (H3O+) and a weak base (NH3) thus water would be made in the neutralization reaction. (Thanks Josh Kaplan 2018)

0r
2C2H2 (g) + 5 O2 (g) —> 4CO2 (g) + 2H2O (g)
|
The chemical reaction that exploded the pumpkin was combustion or redox but the reaction the made fuel, C2H2 was?

This will count as a TEST 3!
a) Complete the Form Below for the Individual portion of the RAT.
b) Complete ticket with your Group!
Individual RAT FORM:
Period 3:
a) Lab 10 in introduction.
11/12 – Thursday “A” Day Homework.
1. RAT #2 in class for Red and Green Teams tomorrow.
2. Please watch the today’s class lecture on Acid Base titrations:
3. Read the notes posted below the virtual Lab:
4. Use the following virtual lab – LAB 10 – to calculate the concentration of the HCl.
Watch the titration or observe. Download the printed graph from the description under the video when you play it Youtube.
On the printed graph of this titration please add the following:
1. Main objective: TO determine the concentration of the acid (analyte).
2. Net ion reaction
3. Mark the equivalence point
4. Calculate the molarity of the strong acid USING the equivalence point (you will need the volume of base added)
I demonstrated this in the class lecture above. You will need a ruler!!
In the virtual lab below :
Thus 25.0 ml of Strong Acid (HCl) in the small beaker was titrated with 0.12M Strong Base , NaOH.
**ACID/BASE TITRATION Curve NOTES:
The new skills that we learned from Thursday’s/ Friday’s Titrations are identifying the parts of a Titration curve. The striking part of the Titration graph is the asymptotic line that occurs as the pH changes becomes exponential changes as the pH nears the equivalence point.
We learned the endpoint in an Acid/Base titration is really an approximation of the equivalence point. The endpoint refers to the volume of titrant added (Standard Base Yesterday) and pH that results when the chemical indicator changes color. This color change will never be exactly at the equivalence point but it approximates the volume of titrant added if the indicator has a color change on the asymptotic line.
Consider 2 titrations like the 2 we did yesterday. We used phenolphthalein which has a color change (turns from colorless to pink at pH changes of 8 – 9). What if we used Thymol blue or Methy red?
Table M
|
Do not forget that these indicators are themselves conjugate acid base pairs in equilibrium.
In the case of Thymol blue
|
Notice in the first Titration which you should recognize as a strong acid / strong base titration, with a pH of the equivalence pH of 7, can utilize both Thymol blue and Methyl red as indicators as the endpoints will be on the asymptotic line. They would have endpoints with approximately the same
volume as the equivalence point.
