How do you know that glassware is clean?
What method should be used to clean glassware in a labortory
What should be given to students before they begin a laboratory experiment?
You should have everything set out correctly.Which means you should have the notebook your going to make observations with and have your safety tools.
What are 5 things you should do when you complete a lab experiment?
When you complete a lab experiment you should first make sure that you have collected all data that you need. Then dispose of all materials used in their appropriate places. Clean your glassware and utensils and put away. Store any other materials that need to be. Wipe down your area. Complete lab reports.
Why must the glassware be dry before beginning and experiment?
Some experiments use chemicals and water, glassware for such experiments must not be dried. But glassware for the experiments that has no water in them must be drived, so water do not get in the reaction. E.g. in Grignard reactions, if water gets in a reaction, alkane will be produce instead of an alcohol. You will get not what you wanted. But if you will perform Acid-Base Reactions, in the end you will get water anyway, so extra water that was in the glassware will not change anything.

Why should heat resistant glassware be used when heating solutions?
Heat resistant glassware is designed to withstand high temperatures without shattering or leaching chemicals into the solution, making it safer for heating solutions. Using heat resistant glassware reduces the risk of breakage and contamination, ensuring the integrity of the experiment or process.
What should every laboratory have?
Every laboratory should have essential equipment such as microscopes, centrifuges, pipettes, and safety equipment like goggles and lab coats. It should also have basic supplies like glassware, chemicals, and consumables. Additionally, a laboratory should have proper ventilation, waste disposal systems, and emergency response protocols in place.
What condition should the lab equipment be at the end of an experiment?
The lab equipment should be cleaned, all chemicals and samples properly disposed of or stored, and all instruments returned to their designated places. It is essential to ensure that the equipment is in good working condition and free from any damages before completing the experiment.
What are three things you should do before you start an experiment?
Prepare your work surface - keep it clear of clutter. Have the necessary equipment ready. Observe safe practices - wear appropriate safety equipment. Have paper & pen ready so you can make notes on how the experiment is progressing.

When would you carry out the calibration procedures for the experiment?
Calibration procedures should be carried out at the beginning of the experiment to ensure accuracy and reliability of the measurements. Additionally, calibration may need to be performed periodically throughout the experiment to account for any changes or drift in the equipment's accuracy.
Why should you never drink from lab glassware?
You should never drink from lab glassware because it may contain residues of harmful chemicals or reagents used in experiments, even if it has been washed. Consuming these residues can be harmful to your health. Lab glassware is not designed for food or beverage consumption and can contaminate your drink.
