Al2O3 issoluble in NaOH and HCl both. Does HCl react with sio2? Silicon oxide is an acid oxide. Therefore, it dissolves in alkaline solutions. Acid and acid oxidedo not react under normal conditions. How is Al2O3 reduced? Al2O3 is reducedby electrolysis at low potential and hi...
The balanced net ionic equation includes only species that are involved in the reaction. It can be found by removing ions that occur on both the reactant and product side of the complete ionic equation. Al(s)+3Na+(aq)+3OH-(aq)= Al(OH)3(s)+3Na(s) ...
To probe into the speciality of NaNO2-Al(NO3)3-NaOH colorimetry for determination of total flavonoids.Method:Make a series of flavonoids and non-flavonoids react with NaNO2, Al(NO3)3, NaOH solution, then mensurate their absorption curves at the range of 400700 nm.Result:At the wavelength500 ...
150μL sample was injected and firstly reacted with a mixture of methyl orange, phenolphthalein and sulfosalicylic acid, and secondly, a mixture of chlorhydric acid, ammonium fluoride and phenolphthalein. Methyl orange and phenolphthalein in the first are the corresponding indicators for the ...
Step 1: Label Each Compound With a Variable Label each compound (reactant or product) in the equation with a variable to represent the unknown coefficients. a NaOH + b Al(NO3)3 = c Al(HO)3 + d NaNO3 Step 2: Create a System of Equations Create an equation for each elem...
Aluminum is an amphoteric metal that can react with bases or acids. Figure 2(b) displays a gradual increase in the mass ratio of AlO2- during the reaction. The mass fractions of AlO2- in the NaOH and KOH systems are similar, reaching 0.157% and 0.149% at 120 min, respectively, due to...
