Gold is the purest of almost all metals and this where the term purity of gold comes from it means the metal is not changed from it's original state in the ground to its state in the shops and stores and no chemicals are added and nothing is changed except for the size and shine. This though is what i have been lead to believe and may not be scientifically correct./
You mean hue?
This term is concentration, expressed in g/l, mol/L, mg/L, etc.
That is a measure of Gold weight, not gold purity. A bar described as "1oz 100 mills 24k GOLD!!!!" contains one ounce of worthless scrap metal, plated with gold with only 100 millionths (0.0001 of an troy oz of gold). In plating, " MIL " stands for thousands of an inch but " MILL " is mass and is millionths of an troy oz (0.0001). So if Gold is trading at $1,300 per troy oz 100 mill is 0.0001 X $1300 = $0.13 worth of gold. eBay seems to be full of these sorts of items. The terms "solid" (meaning full of scrap metal, not hollow) and "pure gold" (meaning the plating is pure, not the scrap metal) are often used misleadingly, while the term "plated" almost never appears. Gold plated items are generally almost worthless; for example, a 1oz 100 mill plated-gold bar might sell for $10 on a good day, while a 1oz solid gold bar currently sells for at least $1000.
The use of the term solvent in this case is not correct.
"Cheap" is a relative term. 10K gold is cheaper than, say, 14K gold, but more expensive than silver. 10K gold is known for being very durable - it's harder than 14K or 18K gold, so it doesn't ding and dent as easily - and could be better for your needs because of this. But I wouldn't generally say that ANY gold is "cheap", regardless of its purity.
The term 14 karat refers to the purity of the gold, and the amount of gold used in the chain, the other 10 parts of the chain metal is not gold. The Y is yellow gold.
Purity.
When speaking of gold, the term 'karat' refers to the purity of the metal. The term 'carat' which refers to weight, is only used to measure the weight of gemstones.

the term pertains to that which is expressed vocally
To answer your question directly, 18k is not measured in carats.Your term '18k' is typically used to describe the purity of gold. In this case, 18k indicates that 18/24ths of the metal mix is gold, 24k, therefore, being pure gold. These karats are spelled karat.For a diamond, 18 carats indicates the weight of the diamond, one carat being equal to .20 grammes. These carats are spelled carat.
No. It's a term like "length", "distance", "area", "volume", "radius", "diameter", "speed", "weight", etc. Any of those terms can be measured and expressed in any system of units.
In gold, a karat is a measure of purity. 24 karat gold is pure gold, while 18 karat is 75% gold. For gems, a carat measures the mass of the gemstone. 1 carat is 0.2 grams.
purity is an optomistic term. by having purity, one showa that they obtain a high average of self-control
White gold is an alloy of gold and at least one white metal, usually nickel, manganese or palladium. Like yellow gold, the purity of white gold is given in karats. The term white gold is used very loosely in the industry to describe karat gold alloys with a whitish hue.
