Water and Alcohol
After decanting the half liquid off of our sludge, we used the distilation process to seperate these two liquids then used flamability to ensure that we we had pure samples of both.
Water &
Alcohol
Water
Water
Decanted half of the liquid on Sludge
Filter more than 100ml
Distill the filtered liquid
Create more than 4 distillates
Test flammability, density, PH, and observe the appearence and scent of a small portion of the last distillate to ensure it is a pure sample of water.
Why this liquid is water:
Properties of water:
- The PH level is 7
- The liquid is not flamable
- The liquid is transparent
- The liquid does not have an odor
- The liquid has a density of 1 g/ml
1. Our PH results are the same as the PH we tested on a sample of water: 7.0
2. The liquid is not flammable, like water.
3. The liquid had the same color and appearance observations as a sample of water: Clear, trasparent liquid.
4. The water did not have much of a scent other than faintly of alcohol, but that was to be expected after a few weeks of sitting in alcohol.
5. The density of the sample should also be 1g/ml, which is the density of water.
Alcohol
Alcohol
Take the first distillate from distillation completed in water's separation technique
Take the first distillate from distillation
Test flammability of alcohol to ensure that it is a pure sample of alchohol
Why is this liquid alcohol?
Properties:
- The PH level is 7.33
- The liquid is flamable
- The liquid is transparent
- The liquid has a strong odor
- The liquid has a density of 0.76 g/ml
1. Our PH results are the same as the PH we tested on a sample of alcohol: 7.33
2. The liquid is flammable, like alcohol.
3. The liquid had the same color and appearance observations as a sample of alcohol: trasparent liquid.
4. The sample smelled like alcohol.
5. The density of the sample should also be 0.7g/ml, which is the density of alcohol.
Salol
Separating
Salol
How we would Separate Salol
Separate some of the wet powder on the bottom of the sludge and place in evaporation dish.
Evaporate overnight.
Mix the powder with alcohol so the calcium carbonate and the sodium bicarbonate do not disolve, but the Salol does.
Filter and evaporate to get pure salol.
Find the PH, flammability, solubility, and observe the odor and chrystals of the salol.
We Know It's Salol Because:
Properties:
- The PH level is 7
- The substance is not flamable but changes into liquid when heated
- The substance is crystally
- The substance does not have a strong odor, but smells faintly of chemicals.
- The substance is not soluble in water and has a solubility of .30 in alcohol
We Know It's Salol Because:
1. The PH level is 7, which is the same as salol.
2. When placed under a flame, the substance had a phase change into a liquid but didn't catch fire. According to the people who salol was assigned to for class data, when the salol melted and changed states of matter, it looked exactly like our liquid sample of salol we are submitting.
3. The substance has a shiny, grainy, crystals. The appearance of the salol crystals had the same observations as the class data - they were irregularly shaped, and though they appeared to be a solid color, on closer inspection they were revealed to be transparent)
4. The odor of the salol crystals had the same observations as the class data: slightly earthy, and a bit like chemicals
5. The substance is not soluble in water, which aligns with the class data.
6. It has a solubility of .30 in alcohol, which is also the solubility of salol in alcohol.
Calcium Carbonate
Dig out some white powder from the bottom of the sludge
Place in evap dish and leave to evaporate
Mix evaporated powder with water
Filter
Calcium Carbonate
Evaporate
Take the powder from evap dish
Test PH, flammability, solubility in water and alcohol, and observe odor and substance.
How we know it's Calcium Carbonate:
Properties:
- The PH level is 8
- The substence is not flamable
- The substence is white and flour like
- The substence does not have a strong odor
- The substence is barely soluble in water and even less in alcohol
How we know it's Calcium Carbonate:
1. We tested the Ph level to be 8, which is the same as calcium carbonate.
2. When our sample of Calcium Carbonate is placed on a scoopula under a flame, is was not flammable.
3. It looks white and grainy, like flour.
4. No significant odor: smells faintly of altoids because it was mixed with alcohol.
5. Barely soluble in water and alcohol.
Sodium Bicarbonate
In order to get Sodium Bicarbonate by itself, we would need to take the residue in the filter from when we got our Calcium Carbonate sample
Evaporate the liquid
Sodium Bicarbonate
This leaves you with a substance which should be Sodium Bicarbonate
Test the substance's flammability, solubility in water and alcohol, PH, and record observations on odor and appearance.
Why is this Sodium Bicarbonate
Why is this Sodium Bicarbonate
Properties:
- The PH level is 8
- The substence is not flamable
- The substence is white, partially translucent, and powdery
- The substence does not have a strong odor
-Is soluble in water
-Is not soluble in alcohol
1. The tested PH level should be 8.
2. The substence should not catch fire with no distinct smell and change the flame color to orange.
3. The substence is white, partially translucent, and powdery.
4. The substence should not have a strong odor
5. The substance should not be soluble in water.
6. It should not be soluble in alcohol.
