Aluminium reacts with sulfuric acid to form aluminium sulfate and hydrogen. What is the volume of hydrogen gas in liters (L) produced at 300 K and 1.0 atm pressure, when 5.4 g of aluminium and 50.0 mL of 5.0 M sulfuric acid are combined for the reaction? (Use molar mass of aluminium as 27.0 g m o l − 1, 𝑅 = 0.082 atm L m o l − 1 K − 1)
And the molar mass is : 2 + 32 + 64 = 98 g / m o l The percentage of oxygen in sulphuric acid : 16 × 4 98 × 100 % = 65.30 % Was this answer helpful?
The molar mass of hydrogen is 1 Molar mass of sulphur (S) is 32 Molar mass of oxygen (O) is 16 Now , 2 (1)+32+4 (16) = 98 Molar mass of sulphuric acid i.e. H 2SO4 is 98.
Sulfuric acid (H 2 SO 4) is a strong acid with hygroscopic and oxidizing properties. Sulfuric Acid is a mineral acid with the chemical formula H 2 SO 4. Sulfuric acid is also known as Mattling acid or Oil of vitriol. It has a strong acidic nature and is corrosive. At higher concentrations, it acts as an oxidizing agent and dehydrating agent.
It forms sulfuric acid when exposed to water. HSO 4– very small hydrogen sulfate ion. Sodium Bisulfate which is the pure substance NaHS0 4 melts at 185°C and begins to lose water with a good deal of spattering. It consists of sulfur atom in the center surrounded by four oxygen atoms form a tetrahedral arrangement.
