Rates of reaction cross; Flashcards
What is the reaction between?
= sodium thiosulfate
= hydrochloric acid
= measuring the rate of reaction between the reaction
What is the reaction between?
= sodium thiosulfate
= hydrochloric acid
= measuring the rate of reaction between the reactio
What does this reaction form?
= sulfur (solid)- yellow solid, makes it cloudy
= sodium chloride
= sulfur dioxide
= water
What is the idea?
= 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
=
What is the method?
= 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
