The solubility of antimonous oxide has been determined in water and in dilute solutions of sodium hydroxide and hydrochloric acid. The equilibria in sodium hydroxide and in hydrochloric acid solutions indicate that the antimony is present in both cases as a monovalent ion. Values of the solubility...
The amount of colloidal stannic acid increases linearly with increase of stannic oxide content of the original sodium stannate solutions. Potentiometric titrations of solutions of varying R (Na 2 O:SnO 2 ) show that adsorption of H + ions occurs. An equation was derived relating the p H ...
Convenience and cost aside, there are a ton of valid reasons to spin up your own boards, ranging from not having to wait for shipping to just wanting to control the process yourself. Whichever camp you’re in, though, it pays to know what’s going on when your plain copper-clad board...
The effects of hydrochloric acid and heavy metal ions addition on some surface properties of SDS were studied. The equilibrium surface tension and critical micelle concentration (CMC) were obtained. Moreover, the adsorption parameters were calculated using the Szyszkowski equation. The kinetics of SDS...
The innovative feature of this research is its comprehensive strategy, which integrates experimental studies and theoretical simulations to evaluate the impact of PETPE on the corrosion control of mild steel in hydrochloric acid. The combined effort has the ability to supply valuable knowledge into the...
athe mass was ground with 1.4 parts sodium chloride for each part of titanic oxide, and mixture was heated to 300 to 700 oC. Free hydrochloric acid was given off. 大量研了与1.4份氯化钠为二氧化钛的每个部分,并且混合物被加热了对300到700 oC。 自由盐酸被释放了。[translate]...
The weight loss of the samples were decreased as the concentration of the inhibitor in the acid medium, suggested the adsorption of inhibitor on the metal surface. Table 1 indicates that the corrosion rate decreased with the increase in EDS concentration. This is attributed to the increase in ...
Making white decorative base paper by impregnating with aqueous titanium oxide solution containing sodium hydroxide as pH adjuster; heating, adding phosphoric acid/sodium aluminate to form aluminum phosphate; adding hydrochloric acid as pH adjuster; drying ...
There are many attempts by scientists in the world to intensify their studies to minimize the possibility of corrosion of carbon steel in strong acid solutions, and the most significant one of these methods is the employing of corrosion inhibitors. A lot of organic inhibitors are employed to ...
is mfd. by mixing and reacting hydrochloric acid with sodium chlorite soln. in a reaction chamber. The addn. quantity and/or concn. of the 2 solns. being added, is regulated by the concn. of chlorine dioxide measured in the soln. downstream from the reaction chamber. Also claimed is ...
