How does salt affect the freezing point of water.

Bearclaws72:

@JustSaiyan

Bearclaws72:

Can you help me?

JustSaiyan:

Hell yes I can.

JustSaiyan:

The salt that is added lowers the freezing point of water because it lowers the vapor pressure of the water. The salt disrupts the movement of these water molecules.

Bearclaws72:

Yah it says I need to create a whole experiment but not perform it

Bearclaws72:

So I hae the question and now the answer

JustSaiyan:

So.....is this the answer you were looking for, or was there something else?

Bearclaws72:

Well I think holdup its not like one question its an assignment

Bearclaws72:

A title The title should identify the property of water that you are investigating. Problem/Question Identify the purpose of your investigation or the question you are attempting to answer. The introduction should include the research and background information you collected before forming and testing your hypothesis. A hypothesis The hypothesis should make a prediction of the outcome of your experiment and should include an explanation of why you expect that outcome. You may use the “if … then …” format for the hypothesis. A list of variables Identify the independent, dependent, and controlled variables in your experiment A step-by-step procedure that tests your hypothesis. The procedure should be clear and detailed so that others can repeat it. The details should be specific in how the procedure changes the independent variable, controls all variables that need to be controlled, and observes or measures the resulting changes to the dependent variable. Data and observations Present all data and observations in a neat and organized manner. Include tables and graphs where appropriate. Conclusion and analysis Your conclusion should discuss the results of the experiment and compare those results to your hypothesis. You should analyze the property of water you investigated and give some real-world applications of the importance of this property. Safety Notes: Always have parent/guardian permission and supervision when performing a lab activity at home. Wear proper protective clothing and eyewear when needed. Be sure to dispose of all materials properly. Always wash your hands carefully after touching anything in a lab investigation.

Bearclaws72:

I can do the hypothesis and procedure just need help with the conclusion and the data

Bearclaws72:

Like should I time how long the saltwater takes to freeze then time regular water?

JustSaiyan:

That sounds pretty good. Also document whether or not the salt effects the formation of the salt.
