Did the test on chemicals and am sure I have the correct answers but it’s marking it as wrong. Please can you check
Hi Susan,
It’s the drag and drop exercise that you seem to have missed. Where you match the chemical to its use. Please have another go.
Kind regards,
Astrid
Hi I can’t get past lesson08 knowledge test, the question with the drag and drop options for water testing. The options aren’t worded very well ie stir,crush&stir,crush to a paste.I have rewatched the video a number of times and there is no reference to the different ways of crushing/stirring/crushing to a paste re the tablets! Also ‘cap tube’ is misleading as you would do this more than once through the entire process. Help!!
Hi Kate,
Under Lesson 08, Chlorine and pH Test Instructions (photometer and comparator), if you scroll past the photometer video, click on “Click here for step-by-step instructions” and then “Free and Total Chlorine”. The steps are written out there using the terms crush, stir etc.
The steps are worded that way as you will only need to form a paste for a specific step etc.
Kind regards,
Astrid
