Rate of reaction:

Question 1

What is the reaction between?

Answer 1

= = sodium thiosulfate
= hydrochloric acid
= measuring the rate of reaction between the reaction

Question 2

What does this reaction form?

Answer 2

= = sulfur (solid)- yellow solid, makes it cloudy
= sodium chloride
= sulfur dioxide
= water

Question 3

What is the idea?

Answer 3

= beneath the conical flask is a black cross- what is being observed
= conical flask has reactants in
= view from top down
= start timer when reactants are mixed until we can no longer see the cross- stop the timer
=

Question 4

What is the method?

Answer 4

= we need a known volume and concentration of reactants
= add sodium thiosulfate
= smaller volume of hydrochloric acid
= swirl and start timer
= stop timer when x is obsercured by the sulfur produced (yellow solid)
= repeat and change the independant variable
