50 Ml Beaker Lab

The 50 mL beaker was filled one third of the way with sodium hydroxide. The base was poured into the buret, and the buret was cleaned with it. The contents were spilled out into the sink.

The 125 mL Erlenmeyer flask was washed with distilled water. The contents were spilled out into the sink.

The 50 mL beaker was filled with 50 mL of sodium hydroxide. The sodium hydroxide was poured into the buret, it was ensured that the buret read zero. The buret was placed in the buret holder and the Erlenmeyer flask was placed to help adjust the height of the buret.

One antacid tablet was taken out of one of the containers. The weight boat was placed on the scale and the scale was zeroed. The tablet was then placed in the boat. The mass was recorded.

The tablet was

The scale was zeroed. A scoopula was used to transfer the ground up antacid onto the weigh boat until the scale read approximately 0.2 grams.

The contents of the weight boat were then transferred into the Erlenmeyer flask.

The flask was taken to the second lab bench and 2-3 drops of methyl orange was added into the flask.

The stir bar was placed in the flask. The flask was placed on the stir plate which was under a buret with hydrochloric acid (Figure 2).

The buret was filled with acid, so that it read zero, using a funnel. The initial amount of acid was recorded. The stir plate was turned on and the buret nozzle was opened.

The speed of the stir bar was increased as the flask filled with acid. The flask was observed till there was a permanent colour change (Figure 3).

Once there was a permanent colour change, the acid was allowed to continue to pour for a short amount of time.

The buret nozzle was closed and the final amount of acid in the buret was recorded. The stir bar was taken out of the flask using a bar magnet.

The flask was then taken back to the first lab bench and placed under the buret with sodium hydroxide. The initial volume of the base in the buret was
