What is the concentration of H in sulfuric acid?
The number of acid hydrogen ions (H+ ) is 2 . Equivalent mass for H2SO4 is 98/2 = 49.
How do you find the concentration of H2SO4?
We want the quotient, Moles of sulfuric acidVolume of solution with respect to the sulfuric acid........... And so, if we have a 1⋅cm3 volume of the acid.......... Concentration=1.84⋅g×98%98.08⋅g⋅mol−11⋅cm3×10−3⋅L⋅cm−3= 18.48⋅mol⋅L−1 .
What is concentrated sulfuric acid?
Concentrated sulfuric acid (95-98%) is very reactive and dissolves most metals . ... Sulfuric acid is is also a popular acid used in gold electroplating processes. Sulfuric Acid is a strongly corrosive, dense, oily liquid and is colorless to dark brown, depending on purity. Miscible with water.
What is the concentration of a sulfuric acid solution if 50 mL of a 0.25 M KOH are needed to neutralize 20 mL of sulfuric acid?
What is the concentration of a sulfuric acid solution if 50 mL of a 0.25 M KOH are needed to neutralize 20 mL of the H2SO4 solution of unknown concentration? 14 m . Initia!
How do I calculate the concentration of a solution?
Divide the mass of the solute by the total volume of the solution. Write out the equation C = m/V , where m is the mass of the solute and V is the total volume of the solution. Plug in the values you found for the mass and volume, and divide them to find the concentration of your solution.
What is the pH of sulfuric acid?
Sulfuric acid (H2So4) has a pH of 0.5 at a concentration of 33.5%, which is equivalent to the concentration of sulfuric acid used in lead-acid batteries.
What’s the strongest acid in the world?
Fluoroantimonic acid is the strongest super-acid known in existence. It is 20 quintillion times more acidic than 100% sulfuric acid, and it can dissolve glass plus a host of other substances.
Is sulfuric acid a strong acid?
Sulfuric acid is a very strong acid ; in aqueous solutions it ionizes completely to form hydronium ions (H 3 O + ) and hydrogen sulfate ions (HSO 4 − ). In dilute solutions the hydrogen sulfate ions also dissociate, forming more hydronium ions and sulfate ions (SO 4 2 − ).
Can acid destroy a diamond?
In short, acids do not dissolve diamonds because there simply isn’t an acid corrosive enough to destroy the strong carbon crystal structure of a diamond. Some acids may, however, damage diamonds.
Why is dilute sulphuric acid stronger than concentrated sulphuric acid?
The presence of water in dilute sulphuric acid increases the hydrogen ion concentration . Hence it is a stronger acid than concentrated sulphuric acid which contains comparatively less water.
Is concentrated sulphuric acid a weak acid or a strong acid?
sulfuric acid: Concentrated Sulfuric Acid
Concentrated sulfuric acid is a weak acid (see acids and bases) and a poor electrolyte because relatively little of it is dissociated into ions at room temperature.
What is the neutralization reaction between sulfuric acid and lithium hydroxide?
sulfurous acid with lithium hydroxide to form water and lithium sulfite. The balanced reaction equation is b. H 2 SO 3 (aq) + 2 LiOH(aq) → 2 H 2 O(l) + Li 2 SO 3 (aq) .
What is the concentration of a hydrochloric acid solution?
Hydrochloric acid is produced in solutions up to 38% HCl (concentrated grade). Higher concentrations up to just over 40% are chemically possible, but the evaporation rate is then so high that storage and handling require extra precautions, such as pressurization and cooling.
What does sulfuric acid look like?
Sulfuric acid is a colorless oily liquid . It is soluble in water with release of heat. ... Sulfuric acid, spent appears as a black oily liquid.
