[Stoves] CARBON "in " and" out" carbonate stove waste .

[Frans Peeters]

Dear STOVERS ,
 
Make yourself a labtest  !
 
Prepare  0,1  MOL=1N  HCL  ( 3,6 g/L ) and   0,1  MOL=1N NaOH ( 4g/l )
solution .
1 MOL  HCl neutralises 1 MOL  NaOH  Purple indicator Phenoloftaleïne .
5 g Sample  + HCL -------> CO2 gas .
,leading  the escaping CO2  into 100 ml  NaOH  0,1 N  .
Titrate restant  NaOH+ indicator  with HCl and calculate carbon from
carbonate .
      Carbon burnable :  5 g sample in creused heated at 850 deg C + Na
NO3 1g
Gives CO2 leaded in 100 ml NaOH gives Na2CO3  .
Restant NaOH + indicator titrated with HCl .
Calculate the CARBON   out –carbonate . 
12g C= 44gCO2=2X 36,5 g HCl=2X 40g NaOH 
2X = valence  of C03- carbonate .
CO2 in fine bubbles into NaOH dissolves .
