Today I have read the Science Practical Assesment(SPA) online. In the online lesson, I've learnt the appropriate equipment to measure a certain substance. I have also learnt the correct way to dilute a soluble solid, the correct way to use the pipette. I have also learnt the different indicators used to identify strong and weak acids. I have also learnt the proper way to do a titration using a burette. I can also identify the errors when doing titration.
