Question 1
Define a limiting reactant.Question 2
How would the concentration change if a 1.0 L flask of 1.0 mol L-1 NaCl were left uncapped on a laboratory bench for several days? Why?Answer 1
A limiting reactant is a reactant that is completely consumed in a chemical reaction and limits the amount of product.Answer 2
The concentration would slowly increase as water from the solution is evaporated. This is because the amount of NaCl in the flask would remain constant while the amount of water decreases.
