water tds

[svrn]

My water bottle says

"TDS at180(degrees sign, i dont know how to do it on the computer) c= 59m/l"

does this mean that the water was heated to 180 degrees celcius? What does this mean?

TDS means Total Dissolved Solids. My labels list this is ppm (parts per million). From your description, I'm not sure how the solids are being expressed.

i know it means total dissolved solids but I dont understand the 180 degrees c

Is it bottled water from a natural hot springs, and does it say mg/l? Hot springs have hot water, expressed in degrees. You said water bottle, but maybe you mean bottle of water.

It says still natural spring water from the famous ducale spring in parma italy.

Are you saying that 180c is the tempurature of the hot spring naturally?

No, the label tells you the weight of the solids in milligrams that were found in one liter of the water after the water was evaporated away.

Either the label or your original post had a typographical error. I say this because m/l doesn't make sense, but mg/l (milligrams per liter) does.

so 180 c is the tempurature at witch the water was evaporated to see the solids?

I think it just refers to the fact that the parts per million of total dissolved solids is 180.
