假如能生成沉淀,那么反应应该是SO2+CaCl2+H2O==CaSO3+2HCl这将是一个弱酸制强酸过程,但是CaSO3不是像BaSO4,AgCl那样即不溶于酸,也不溶于水的沉淀,而且不满足复分解反应发生的条件,因为HCl可与CaSO3反应掉(反过来可以... APP内打开 结果2 举报 没有沉淀。SO2+H20=H2SO3H2SO3与CaCl2不反应 查看完整答案 结果3 ...
This in turn increased the flux from 9.31 to 11.22 L/m2 h (when the pH was increased from 7 to 10) when 0.1 g/mL of STPH is used as draw solution. Interestingly, reverse salt leakage was maintained at same level when pH increased from 7 to 9 as multiple negative groups in STPH ...
but whether it in R, R′ or in R′′ correlograms, there correlations coefficient were not reach the 0.01 significance level (Table4). That may be due to the low concentrations of E-Pb in the agricultural

8(a). As seen, under the same load stress level, aluminum foams with higher porosities do not always display poor energy absorption capacity, which is quite different from the tendency of W-ε curves, in which the energy absorption capacity drops monotonously with P. It can be seen from ...

As the replacement level of fly ash increases, the chloride binding by C-S-H increases first and then decreases. The amount of bound chloride by C-S-H increases linearly as the pH of the exposure solution decreases.doi:10.1016/j.cemconcomp.2018.12.011Qiao, Chunyu...

As the CaCl2 concentration increased, the electrical conductivity (EC) of soil leachate and the level of salt exchangeable cations (K+, Ca2+, Na+, and Mg2+) significantly increased whereas the acidity (pH) significantly decreased (all p ≤ 0.05). No statistical difference was observed in leaf...
