All, doing a 5 minute freewrite. Thank you for reading.
Jeremy found many glassware in the lab have various stains that are uncleaned after completing his last project. And it is time for him to do a deep cleaning of these apparatus before embarking on his next project otherwise leftover stains might cause inaccurate results or affect path of reaction.
To clear off all the stains, he took out a bottle of sulphuric acid and started pouring it into 2 plastic tubs. For the first tub after pouring in the acid, he put in all the dirty apparatus into it. And after soaking for a good 1 hour, he remove item by item and do scrubbing of the apparatus in the second tub. One by one, the apparatus were carefully scrubbed by Jeremy and then put onto the drying rack to be dried.
The next day morning when Jeremy came into the office, he was so glad that all the apparatus has become squeaky clean once again and he let out a smile, glad that he had done a good cleaning and ready for his next project.
