Is eutectic point and eutectic mixture the same thing? If not what is the difference between the two?
Thanks in advance.

That site Ms. Sue gave you is good one. The eutectic point is the same as the eutectic temperature described in that article.
The eutectic point and eutectic mixture are related but not exactly the same thing. Let me explain the difference between the two.
The eutectic point refers to a specific temperature at which a eutectic mixture undergoes a phase change. It is the lowest possible temperature at which the components of a mixture can coexist in a completely homogenous solid state. Below the eutectic point, the mixture will have separate solid phases, while above it, a single solid phase will be present.
On the other hand, a eutectic mixture is a specific type of mixture that exhibits the eutectic behavior. It is formed by combining two or more substances that are mutually soluble in the liquid state but form distinct solid phases when cooled below the eutectic point. A eutectic mixture typically has a unique composition that allows it to have the lowest melting point possible for that combination of substances.
To determine the eutectic point, one needs to perform experiments by systematically varying the temperature and observing the behavior of the mixture. In the process, one can identify the temperature at which the mixture experiences the phase change and becomes eutectic.
So, in summary, the eutectic point refers to the specific temperature at which a eutectic mixture undergoes a phase change, while a eutectic mixture is a specific type of mixture that exhibits eutectic behavior.
