Examples of Equations you can enter: KMnO4 + HCl = KCl + MnCl2 + H2O + Cl2 Instructions. To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above. Should the quantity of Ca(OH)2 used be sufficient to raise the Na2S content of the treated liquor to above the maximum permissible Na2S value for that particular operation, after the Ca(OH)2 treatment, the liquor in tank 32 may be gassed with enough H2S, preferably pure, to lower the Na2S content to the desired amount.

Treatment chemicals used were: lime (Ca(OH)2), sodium sulfide (Na2S), alum (A1K(S04)2), and ferrous sulfate (FeS04). Chromium, aluminum, and titanium concentrations were reduced to below 0.5 mg/2. at pH 8 by lime addition. Alum was effective for titanium removal (probably due to pH effects) and marginally effective for vanadium and arsenic (+5 1 Ca(SO4)2 + NaCO3 ‡ NaSO4 + CaCO3 2 Cl + NaBr ‡ NaCl + Br 3 Al + Na(OH)2 + H2O ‡ NaAl(OH)4 + H2 4 C4H8 + 4O2 ‡ 4CO2 + 4H2O 9.

The oxidation state of any chemically bonded carbon may be assigned by adding -1 for each bond to more electropositive atom (H, Na, Ca, B) and +1 for each bond to more electronegative atom (O, Cl, N, P), and 0 for each carbon atom bonded directly to the carbon of interest. For example: propene: CH3-CH=CH2; lauric acid: CH3(CH2)10COOH
