RUSHES After and before 6x pics NO RUSHES Growth at sites years on

I. RUSHES in Palm Bush
II. CLOSE UP Rushes in Palm Bush
III. RUSHES Partition

AFTER: Application of:
Na2HCO3 Crystals[Cryst.] =
Sodium carbonate[Cryst.] =
Salt of carbonic acid[Cryst.] =
soda ash = washing soda[Cryst.] [handful on two occasions]

The possible explanation:
SOLVAY [Erich, Swede 1891] PROCESS in generation Na Carbonate

SOLVAY ecologically sustainable [wikipedia]

1. NaCl + NH3 + CO2 + H2O → NaHCO3 + NH4Cl

Sodium chloride + Ammonia = Catalyst + Carbon dioxide + water
Table/Sea Salt buffer in basic pH, bubbles up
if < pH = acidic-
No reaction

→ Sodium bicarbonate + Ammonium Chloride
Baking Soda recycled into NH3
&Reused + Brine
in reaction 1.

2. CaCO3 → CO2 + CaO

Calcium carbonate 950-1100OC Carbon dioxide + Calcium oxide
Limestone Heat bubbles from Quicklime
reaction 1. Base

3. CaO + NH4Cl → CaCl + 2 NH3 + 2 H2O
Calcium oxide + Ammonium chloride →
from react.2. from react.1. Recycled to
Brine + NH3
for react.1.

→ Road Salt + Ammonia + Water
Waste prod.

4. NaHCO3 → Na2HCO3 + H2O + CO2
Baking 160-230OC Sodium + water + carbondioxide
Soda Heat carbonate Reuse in
Calcination Soda ash react.1.

SOLVAY Process TOTAL Reaction

2 NaCl + CaCO3 → Na2CO3 + CaCl2
Table Calcium Na carbonate Calcium
salt carbonate soda ash chloride

Explanatory Note:

I.Lime = CaO or Ca OH
Calcium or Calcium
oxide hydroxide
Building Mortar + Waste Water treatment with Fe2+S

II.Limestone = chalk = cement or concret or mortar = CaCO3
III. Agricultural Lime = crushed Limestone

CaCO3 ↓ Heat

carbonate ↑ Quickline = Base
↓ +H2O
Slaked Lime

Graded as per Mohs scale for hardness

IV. Carborundum Stone = Silicon carbite stone SiC
V. Quarz = SiO2 = Silicone dioxide
VI. Difference between Na2HCO3 versus NaCO3 is H2O + CO2
washing vs sodium
soda bicarbonate
salt of
carbonic acid

A) Na2HCO3 produced from Salt + Limestone = SOLVAY
Sodium carbonate NaCl + CaCO3 = Process

B) Na2HCO3 + H2O → CH2Na2O4
Na carbonate + water → Sodium carbonate monohydrate

Apology for diagram display of:
Limestone to Quicklime to Slack lime,
the post appears to LEFT boarder when "submit" is clicked.
Pics viewable!
