Testing for gases on chapter 18 please I understand more than my teachers when I watch your videos Thank you

What was the ratio in the Potassium Iodide and Sodium Thiosulfate solution?

[@chatzida]

This is an excellent and really informative video! All information needed to implement the experiments in school lab is provided!

[@royalsocietyofchemistry4447]

Thank you for the feedback. We want our videos to support live practical work and make sure everyone can get the most out of the opportunities they have to do it. As you have pointed out the additional resources suggest how ...

Excellent sir.

5:58: "one mole of gas occupies 24 decimeters-cubed at standard temperature and pressure". No, that's not correct. That should be_ one mole of gas occupies "22.4" decimeters-cubed at STP. Actually, ONLY at Room Temperature and Pressure (rtp), one mole of gas occupies 24 dm^3".

Ah the old RTP vs STP chestnut - easy to confuse! Well spotted.

Great video but why aren’t they wearing gloves?!

[@royalsocietyofchemistry4447]

Thank you for your comment. Gloves are not routinely required by technicians, teachers or students carrying out practical work in science and should be used only when guidance from CLEAPSS, SSERC or your equivalent safety body requires them, or your own risk assessment deems it necessary (usually if the user has skin conditions or injuries). In this practical, the solutions used do not require gloves to be worn. You can find more information about setting up this practical, including safety, along with questions and activities in the supporting resources available here rsc.li/3hmgils

In industry you will use materials safety data sheets to determine the appropriate protective equipment and precautions when handling various chemicals. These precautions should also extend to the "expected" products and potential products of a reaction. At very dilute concentrations such as those used in schools most chemicals are relatively harmless. However, as a technician if you are frequently handling chemicals that are moderately irritating or corrosive then it is good practice to were gloves and goggles.
