After dissolving our impure naphthalene in methanol the solution looks red. what could have happened

Welcome to the lab! Today we are goingto learn how to purify a solid. To do so,we will recrystallize our impure solid,then use suction filtration to separate itfrom our solvent, and finally, perform amelting point range to determine itspurity.Let's get hands on!This bottle contains the solid that weneed to recrystallize. This chemicalcompound is called naphthalene and isnormally white in color, as you can seein the bottle in the right corner of thefumehood.However, this naphthalene containsimpurities and appears red. We need toremove them, and the recrystallizationmethod can help us do this!In the recrystallization process, wedissolve a solid that contains impuritiesin a solvent.This solvent should keep the soliddissolved when it's hot, but NOT whenit's cold.You may have seen that your handslook orange! No worries, I alreadyequipped you with thermal-resistantgloves, since we are going to work withhot substances, and you are alsowearing a lab coat.The process to perform recrystallizationis as follows:First, we heat up our solvent to itsboiling temperature. Then. we dissolveour solid while the solvent is hot. Finally,we cool down our mixture slowly to allowthe formation of crystals.If you follow this procedure you will havefewer impurities in your crystals than atthe beginning! Isn't that amazing?Let's start by first choosing the solventthat we need to use.Normally, its a long and complicatedprocess to decide which solvent is bestfor our solid. But don't worry, in thissimulation I have picked the best one foryou.We are using methanol as a solvent. Becareful, methanol, as with many othersolvents, is flammable.You can read more about the propertiesof methanol and naphthalene in theTHEORY PAGES.Once we know which solvent we areusing, the first thing that we should do isprepare our solid. In this case, the solidis our impure naphthalene.Well done, you just weighed out 2 g ofnaphthalene.What color is our solid? Naphthalene isusually white, so why is our solid red?c) This naphthalene contains redimpuritiesThis naphthalene contains redimpurities. Precisely! There are somered impurities in our solid, let's try toremove them!Awesome, one step closer!We now need to prepare our solvent.As you may remember, we are usingmethanol as our solvent because oursolid dissolves well in it at hightemperatures. but not at low
