Limewater is the common name for a diluted solution of calcium hydroxide. Calcium hydroxide, Ca(OH)2, is sparsely soluble in water (1.5 g/L at 25 °C). Pure limewater is clear and colourless, with a slight earthy smell and an alkaline bitter taste of calcium hydroxide. The term lime refers to the alkaline mineral, and is unrelated to the acidic fruit.
Limewater is prepared by stirring calcium hydroxide in pure water, and filtering off the excess undissolved Ca(OH)2. When excess calcium hydroxide is added to limewater, a suspension of calcium hydroxide particles results, giving it a milky aspect, in which case it has the common name of milk of lime. Milk of lime or a saturated solution of lime (limewater) has a pH of 12.3. It is basic in nature.
Carbon dioxide passed into limewater gives a milky solution. This is due to the insoluble suspension of calcium carbonate formed:
If excess CO2 is added, the following reaction takes place:
The milkiness disappears since calcium bicarbonate is water-soluble.
I keep floating down the river but the ocean never comes
Since the operation I heard you're breathing just for one
Now everything is imaginary, especially what you love
You left another message said it's done,
It's done
When I hear beautiful music it's always from another time
Old friends I never visit, I remember what they're like
Standing on a doorstep full of nervous butterflies
Waiting to be asked to come inside
Just come inside
But I keep going out
I can't sleep next to a stranger when I'm coming down
It's 8 a.m. my heart is beating too loud
Too loud
Don't be so amazing or I'll miss you too much
I felt something that I had never touched
Everything gets smaller now the further that I go
Towards the mouth and the reunion of the Known and the Unknown
Consider yourself lucky if you think of it as home
You can move mountains with your misery if you don't
If you don't
It comes to me in fragments, even those still split in two
Under the leaves of that old Lime Tree I stood examining the fruit
Some were ripe and some were rotten, I felt nauseous with the truth
There will never be a time more opportune
So I just won't be late
The window closes, shock rolls over in a tidal wave
And all the color drains out of the frame
So pleased with a daydream that now living is no good
I took off my shoes and walked into the woods
