Abstract:
The two natron samples were collected from different location of different
environments .The samples were analysed qualitatively and quantitatively by
standard methods of analysis to determine the chemical composition and the
concentration of each component .
The effect of natron on chemical structure of Toombak was studied.
The analytical techniques used in this study are:-
Flame Emission spectroscopy which was used to determine sodium and
potassium ions, content and the results was 8.4%,0.45%,(sample A) 14.33%
,2.03% (sample B) respectively.
Volumetric analysis was used to determine the carbonate and bicarbonate the
results obtained were 8.70%, 6.25% (sample A)، 22.5%, 10.67% (sample B)
respectively. While total alkalinity of sample (Omdurman market used for
toombak prepared) was found to be 2800 .
The percentage of silica was determined gravimetrically the result obtained
53.20%, 36.87% respectively.
Matter insoluble in water and insoluble in acid was determined for the sample
(Omdurman market used for toombak preparation) and it was found to be
60.07%, 63.55% respectively.
Finally the pH of the two samples of natron was found 9.8 and three toombak
samples were found 5.6 to 5.7.
