RSC Belgium Top of the Bench 2019

Our annual 'international eliminator' for the Royal Society of Chemistry's Top of the Bench (TOTB) competition was held at the British School of Brussels (BSB) on Saturday 23 November 2019 with teams from Belgium and Luxembourg taking part. In total 12 teams from 6 schools participated. An exciting afternoon of chemical problem solving ended with the announcement of the 2019 winner of the Keith Price Cup: Team Sulfur from St George's School in Luxembourg. They will now represent RSC Belgium at the TOTB grand final in the UK in 2020.

The teams completed individual written question papers and then enjoyed a challenging team Practical Problem Solving Exercise. As usual both the 'hands-on' practical and the paper-based component were developed by our resident competition guru, Rita Woodward. The competition was designed to really test the teams’ chemistry knowledge and problem-solving abilities and encourage young talented chemical scientists to consider further education and careers in Chemistry.

The individual scores from the written paper were added together for each team with the placings from the practical session to give an overall score.

Members of the winning Sulfur team (pictured above) received our TOTB Keith Price Cup as well as some RSC goodies. All the student participants will receive a certificate.

Conkering foams

The practical component of the challenge was based around making and measuring 'foam'. Saponins are natural detergents found in many plants including the seeds of the horse chestnut tree - traditionally called ‘conkers’. Saponins contain both water soluble and fat soluble components and as a consequence form stable foams. 

The teams were asked to prepare a detergent extract from saponin present in conkers and then, in the shortest time produce a declared volume of chemical foam from a mixture of the liquid detergent, sodium hydrogen carbonate and lemon juice.

The judges were particularly impressed by the approach to and quality of the practical work this year and once again the outcome for the practical was very close with hardly anything between the teams. However, when taken with the performance on the written papers the Team Sulfur from St George’s International School was the clear winner.

Commenting on the practical competition, Rita Woodward said: "Overall I was impressed. It was very pleasing to see how well the teams worked together to make good use of the equipment and the time allowed."
