a student investigated the rate of reaction between sodium thiosulphate and dilute hydrochloric acid
the student placed a conical flask over a cross on a piece of paper
the student mixed the solutions in the flask
the solution went cloudy
the student timed how long it took until the cross could not be seen
the equation for the reaction is :
Na2 S2O3(aq) + 2HCl(aq) = 2NaCl(aq) + H2O(l) + SO2(g) + S(s)
explain why the solution goes cloudy

You are forming a Sulfur precipitate in the solution which is likely why it goes cloudy.
