To demonstrate that matter is conserved during a chemical change or reaction, the best procedure would be:
Find the mass of an acid and a base. Combine them to produce water and a salt. Find the mass of the water and salt.
This procedure involves a chemical reaction where the reactants (acid and base) transform into products (water and salt), allowing you to directly observe the conservation of mass before and after the reaction.
