EDPA WLMs retards the reaction rate of HCl with the carbonate rock and uniformly etch at 150 °C, showing great potential for application in the acidizing stimulation for high-temperature oil reservoirs. 图1 EDPA-20%盐酸与...
Our experimental results showed that at equal HCl concentration levels, De was significantly decreased at elevated pressures, due to the impact of CO2 produced by the HCl-carbonate reaction. There was approximately 23% decrease in the diffusion coefficient value when compared with 1000 psi results ...

Calcium carbonate reacts with aqueous HCl to give CaCl2 and CO2 according to the reaction given below CaCO3(s)+2HCl(aq)→CaCl2(aq)+CO2(g)+H2O(l) What mass of CaCl2 will be formed when 250mL of 0.76 M HCl reac ts with 1000 g of CaCO3? Name the limiting reagent. Calculate the...
NaCl + H2CO3 = HCl + Na2(CO3) is a Double Displacement (Metathesis) reaction where two moles of aqueous Sodium Chloride [NaCl] and one mole of aqueous Carbonic Acid [H2CO3] react to form two moles of aqueous Hydrogen Chloride [HCl] and one mole of aqueous Sodium Carbonate [Na2...
the reaction of (1) was identified by taking the aqueous solution obtained in the identification (1) and showing chloride (General 0301). examination the pH value should be 6.0 to 7.0 (General 0631). sterile take this product, inspection according to law (General 1101), should comply with ...
When MgO is prepared from MgC2O4·2 H2O, the reaction occurs in the bulk material, whereas when MgO is prepared from Mg(OH)2, the reaction hardly progresses after HCl adsorbs onto the MgO surface. The order of magnitude of HCl removal was consistent with the base catalytic activity ...
Hi all, I hope you guys can help me out here. My question relates to the reaction of sodium carbonate with hydrochloric acid. I know that Na2CO3(s) + 2HCl(aq) --> 2NaCl(aq) + H2O(l) + CO2(g) But what about Na2CO3(aq) + 2HCl(aq) ...
