All the tests are carried out in a solution that simulates the composition of the pores in chloride-contaminated carbonated concrete. The carbonated solution (CS) contained Na2CO3(0.0015mol L1), NaHCO3(0.03mol L1) and NaCl (0.1mol L1), resulting in [Cl]/[OH]=10000. Inhibited solutions (...
The spectator ions are present on both the reactant as well as product sides of a chemical reaction. They do not participate in a chemical reaction. By removing these ions we can easily get to know about those species that par...
In the second step, i.e. when R∗<R<2, the precipitation of the excess of FeIIaq present in solution leads to the formation of Fe(OH)2. The (x,R∗) of points E* presented in the mass-balance diagram in Fig. 4 increases roughly linearly according to R∗=αx where α=7±...

Moreover, NaNO3 is principally present in the coarse mode, which is out of the ACSM size range. Consequently, the discrepancy between the two instruments during marine air mass influence might result in a size cutting effect, while it may also indicate the presence of two types of nitrate ...
Chemical precipitation is the most widely used method for heavy metal removal from water, and its effectiveness depends on several factors such as the type and initial concentration of heavy metals present in water, the precipitating agent used and the pH of the solution. In this paper an ...
Since Cr(VI) is present in anionic form; it can be eliminated from the loaded adsorbents using bases like NaOH, Na2CO3 or NaHCO3.MishraDepartmentS.DepartmentP.DepartmentEBSCO_AspCurrent ScienceMishra S. Adsorption-desorption of heavy metal ions. Curr. Sci. 2014;107:601-612....
Indicate which ions are present in the solution for the water-soluble compound. Na2CO3 Determine whether the following compound is soluble, moderately soluble, or insoluble in water: Al(NO_3)_3. Determine whether the following ...
Results of this study indicated that the oxidation power of the PS/Fe0process was inhibited in the dye solutions containing carbonates, and the efficiency of SRF3B decolorization decreased with increasing concentration of Na2CO3. A short period of ultrasound (US) irradiation can significantly enhance ...
