# data[].attributes.body
Sludge is the experiment to analyze an unknown substance that can be filled with powders, metals and other liquids.
BLUE:ARE FOR TEST
PURPLE: BOILING/MELTING
GREEN:DENSITY

# data[].attributes.body
How ever much you fill the graduated cylinder with of liquid.

# data[].attributes.body
Water and alcohol testing with powders

# data[].attributes.body
See if soluble or insoluble in water and alcohol. Find melting point, MMP OR EVAP dish. Drop to drops of acid on substance to see if there is reaction.

# data[].attributes.body
Less than 10mL

# data[].attributes.body
Liquid:How much the empty graduated cylinder is then with liquid.
Metal:Weight the metal.

# data[].attributes.body
When the substance starts to bubble and the temp. begins to plateau.

# data[].attributes.body
First find the density of the metal. Then put acid on it and see if it has a reaction. Next use a magnet to see if it is magnetic.

# data[].attributes.body
Used to separate a powder from a liquid.

# data[].attributes.body
To separate two or more liquids.
You know your done once you the liquid stops plateauing. Or have enough liquid in your tube.

# data[].attributes.body
When you find the volume and mass. Then divide mass by volume. Always include units D=M/V. Round volume to the nearest tenth. Units in final answer is g/mL.
DON'T NEED DENSITY FOR POWDERS.

# data[].attributes.body
USE ORIGINAL LIQUID TO FIND POWDER
first sign of melting.
300 degrees Celsius

Evap dish        Melting Point
^^^DO THIS IF LIQUID DOESN'T MELT AT 100 OR BELOW

100 degrees Celsius

MMP
Starts at 23 degrees Celsius
Turns clear

# data[].attributes.body
Density, mass of graduated with liquid subtracted by mass of empty graduated cylinder. Gives you mass. Then divide that by how ever much the volume of the liquid is. Next find boiling point, wait for liquid to bubble. Then do flammability test and sugar test. For sugar just drop a pinch into the test tube with the liquid, shake it and see with the sugar dissolves.
