21mL nitric acid solution that completely neutralizes 25mL of a 0.3M solution of NaOH?HNO3(aq)+NaOH(aq)=NaNO3(aq)+H2O(l) 相关知识点: 试题来源: 解析 21毫升硝酸溶液,完全中和25毫升的0.3 M氢氧化钠的解决方案? 硝酸溶液(aq)+氢氧化钠(aq)= NaNO3(aq)+水(l)...
molarity of a 70 wt. % nitric acid the number of moles of HNO3present in 1 liter of acid needs to be calculated. Knowing the density of the acid to be 1.413 g/mL, we can calculate the weight of 1 L of 70% HNO3to be 1413 grams. Knowing that the solution is 70 wt % would ...

To find the molarity and molality of a 13% solution (by weight) of sulfuric acid with a density of 1.02 g/mL, we will follow these steps: Step 1: Calculate Molarity 1. Understand the formula for molarity: Molarity (M)=Percentage by weight×10×Density (g/mL)Molecular weight (g/mol)...
Systematic studies have been carried out to optimize various parameters, such as acid molarity, contact time, and batch size, required to remove uranium preferentially from the solid waste leaving behind Pu and other impurities. The concentrations of U, Pu, Ag and other impurities during this ...
Nitration of phenol in reversed micelle systems with dilute nitric acid, CHCl3/CTAC/H2O (2.0 mol dm 3 HNO3 in the 1.0% (v/v) H2O phase), was performed at 35 °C to obtain 2- and 4-nitrophenols, where CTAC represents cetyltrimethylammonium chloride. In similar CTAC and AOT ...
Oxidation of bromideSalt effectIn a previous paper, we have reported that dilute nitric acid in reversed micelle systems can oxidize the Br- ion to Br_2 and proposed that the nitryl (or nitronium) ion NO_2~+ should be the active species in the oxidation process. Nitration of phenol in ...
