Pour 100 mL of concentrated hydrochloric acid into 100 mL of water and mix.
Operate in a draft.
The marker alignment of the Messzylinder is only seen from a distance.
Normally, concentrated hydrochloric acid is added to the water in the beaker and transferred to the reagent bottle after the temperature has cooled to room temperature.
The water and hydrochloric acid are mixed in the reagent bottle to avoid the risk of transporting a beaker containing 6 mol/L hydrochloric acid.
The reagent bottle is covered with plastic wrap and the lid of the reagent bottle is placed on the reagent bottle after the temperature of the liquid has cooled.
