Some chemical factories use the chloralkali process to make substances from brine, which is a mixture of sodium chloride (NaCl) and water (H20). In this process,
factory workers send currents of electricity through the mixture, causing sodium
hydroxide (NaOH), chlorine gas (Cl2), and hydrogen gas (H2) to form. These
substances can later be used to create other chemicals like bleach and drain cleaner.
In the chemical reaction described in the passage, which of the following are reactants?
Select all that apply.
sodium hydroxide (NaOH)
sodium chloride (NaCl)
hydrogen (H2)
water (H20)
