Experimental Techniques Flashcards
1
Q
Mass Change
A
mass decreases if gas is produced
mass-time graph: tangent to find rate
2
Q
Volume of Gas
A
v of gas produced - time: rate is gradient
gas syringe
underwater upside down measuring cylinder
3
Q
Titration
A
small samples of reaction removed at regular intervals
titrated to find [] of reactant/product
concentration-time graph
