Why is the main reason to clamp the flask in place?Group of answer choicesAs the funnel is top heavy, it might tip over.The vacuum line creates an imbalance, potentially tipping the flask over.Actually, it's not an issue if you just hold the flask in place yourself.

During a filtration, if you still have solid in your flask that you need to get onto the filter funnel, you should use the filtrate from your filtration to wash them out.Group of answer choicesTrueFalse

What size of flask should you use? Consider the following factors then give your answer:The total volume of liquids that you will mix.The shape of a conical flask - consider that:A rapidly-effervescing (or boiling, or foamy) solution can easily overflow if it rises up the inside of the flask. Will H2O2 release oxygen gas?Stirring will be ineffective if the flask is under-full or over-full. The ideal liquid level is generally not much higher than where the flask begins to taper inwards.Cooling will be more effective if the flask can be immersed in an ice bath to at least the level of the solution. The typical practice to not fill a flask more than 25-50% full (aim for 1/3rd)That only certain flask sizes are availableThat stirring will be ineffective if the flask is over-full or under-full.

Describe what happens when the flask is heated up and then allowed to cool slowly.

. A volumetric flask was used to make the diluted solutions in this experiment. If you accidentally filled the flask above the mark.a. Would the concentration of solution be higher or lower than desired? Explain.
