1	HCl Pool Acid	370	g/L	319.0238984	g/kg									1 dKH =	17.848	mg/L of CaCO3		0.0001783195124	mol/L of CaCO3 per dKH
2														calcium carbonate molar mass	100.09	g/mol
3	Step 1	dilute fuming pool acid to make it safer/easier to work with. ie not fuming anymore
4	Acid pH	-1.006373863	pH				TapWater pH	7.6

9		After mixing --->		Total H+	0.09434580396	moles H+						Ca++ + CO3-- + H+ + Cl- -> Ca++ + HCO3- + Cl-					Legend
10				Total Vol	5.01	L						2CaCO3 + 2HCl -> CaCl2 + Ca(HCO3)2					input variables
11				H+ conc	0.0188314978	M (mole/L)						CO3-- + CO2 + H2O -> 2HCO3-					caution acid
12												NH3 -> NO2 -> NO3-					very strong FUMING acid
13				pH	1.725115136							CaCO3 + 2H+ + 2Cl- -> CaCl2 + H2O +CO2					output data
14																	very wrong
15	Step 2	mix "diluted" acid into bucket for water change. Still adults only					mixing bucket	48	L
