why is coffee a solution in chemistry?

The word "solution" is synomynous with the phrase "homogeneous mixture," which means that it is uniform throughout.  When we say that coffee is a solution, we are saying that it is uniform throughout, which, for practical purposes, it is.

I agree with the first poster on C and E, but I'm not sure if A is also.  A solute dissolving in a solvent seems like a chemical process to me, but I don't remember for sure.

Coke....   because it is a dark cola.  Coffee and tea will also do the same thing.

Chemistry is the study of the make-up and properties of matter.

Caffeine by itself doesnot raise Insulin levels - sugar in your coffee will.\n\nWhen sugar enters the blood stream, insulin is secreted by the pancreas to convert the extra glucose into glycogen and fat.

Most chemical reactions, both in nature and in the laboratory, take place in a solution.\n\nFor ionic chemicals, it is the polarity of the solvent (usually water) which allows the separation of the ions so that the reaction can take place.\n\nFor non-polar chemicals, the solvent (often a non-polar one) allows for the chemicals to come into contact with one another and to regulate the speed at which the reaction takes place.\n\nAll biological chemistry depends upon reactions which take place in water (as a solvent).  This is especially true of reactions involving enzymes.

Chemistry is the basis of all science. Without it, many of the technological advances would not have been able to occur. There is much more you could use but I'm just too tired right now to think of anything else. Sorry.

to determine whether an acid or a base is soluble in say the universal polar solvent water, u should be knowing whether the substance is strong or weak\nnow bases like NaOH, CsOH, RbOH, Mg(OH)2 are strong bases and in solution they give us the cations and anions(mostly the hydroxyl grp)\nbases like Be(OH)2, Fe(OH)2 or 3, Cu(OH)2 or any of their oxides are weak and hence in solution they do not undergo complete dissociation and most of these are insoluble\nso in case ur not in a lab, the only way is to identify their degree of weakness

syrup is a solution, it is clear and has much sugar dissolved.\nmilk is not a solution, it is not clear, particles are too big\neye drops are solutions, clear\ntomatoe juice is not, not clear\ntap water is, many minerals dissolved

Yes, Coffee has a much higher total in-vitro antioxidant activity than other commonly consumed beverages. This is due in part to intrinsic compounds of coffee such as chlorogenic acid, in part to compounds formed during coffee bean roasting such as melanoidins and in part to as yet unidentified compounds. It is widely believed that antioxidants protect against the development of chronic diseases including heart disease and cancer but whether the antioxidants characteristic of coffee have such effects remains to be determined .

yes it does. coffee has been scientifically proven to speed up the beating of the heart. the faster the heart beats, the more blood pumped through your lungs. blood carries oxygen, and oxygen helps asthma.

Heating the soda will easily drive the CO2 from solution.  \nCO2 is not naturally very soluble in water because it is nonpolar, while water is polar, and for gases, heating decreases solubility enough to allow nearly all of it to come out from solution.

True. water is essential for the transport of nutrients within them, since it is the "universal solvent".

If when you mix the two together the solution turns clear, you have a solution.  If it makes a cloudy mixture, or if there is visible solid on the bottom, you have a heterogeneous mixture, or a non-uniform mixture, which is not a solution.

the powder is the solute and the water added is the solvent.

A lot of research has been done on coffee to refute many early misconceptions that coffee is bad for you.  With caffeine as its active ingredient, the problems associated with it include increased blood pressure, increased heart rate, and increased risk of irregular heartbeat.  There are ongoing studies to show whether coffee is related to breast cancer and osteoporosis. Many of these negative effects are due to overconsumption, so coffee should be taken in moderation, much like any other substance.\n\nHowever, a lot of new research has shown that coffee might even be good for you.  According to a Harvard Research newsletter, coffee has been indicated potential decreases in risk for type 2 diabetes, gallstones, colon cancer, liver damage in people at high risk for liver disease, and Parkinson's Disease.  Coffee has also been shown to increase memory, alertness, and even endurance in physical activities.
