States of Matter

Postby Ramneet Sandhu 3D » Thu Oct 03, 2019 9:55 am

Do the states of matter in a chemical equation (gas, liquid, aqueous, solid) matter when we are solving problems for molarity/dilution? Is there anything we have to do to account for the differences in forms? Thanks!

Typically, states of matter do not matter when we are solving problems for molarity/dilution as long as you know what is being diluted. However, in the later sections where we cover gases, we will learn that each mol of any gas in its ideal state takes up 22.4 L, which might come in handy in the near future.

No it doesn't matter.

As of right now, they do not matter as much, but in the future they will matter a lot. They are really telling, especially when we get into deeper chemical equations. It is also super helpful for when we do lab and see what state of matter we need to expect.

For basic molarity and dilution problems, I don't think states of matter will make a difference when mixing solutions together. However, when we learn about precipitates, there will be side reactions that we will have to account for. Also, states of matter will matter if we go over entropy.

The states of matter do not matter when balancing a chemical equation

For the problems that we are currently solving, I don't think the states of matter make a difference.

The states should not really matter for dilution reactions especially for the level of chemistry that we are doing for this class. So I don't think we need to factor in the states, unless it were something like enthalpy change and switching from sublimation (from solid to gas) and we need to calculate the enthalpy change.

It doesn't matter when solving problems for molarity/dilution, but it is is important to include when writing out the chemical equations.
