Chemical reaction: HSO₄⁻(aq) ⇄ H⁺(aq) + SO₄²⁻(aq);
or HSO₄⁻(aq) + H₂O(l) ⇄ H₃O⁺(aq) + SO₄²⁻(aq)
Ka₂ = [H⁺]·[SO₄²⁻]/[HSO₄⁻]; Ka₂ = 1.0·10⁻².
[H⁺] is equilibrium concentration of hydrogen cations.
[SO₄²⁻] is equilibrium concentration of sulfate anions.
[HSO₄⁻] is equilibrium concentration of hydrogensulfate(bisulfate) anions.
Answer:
4.18 grams

Answer:
what is the pOH of a with a pH of 10 14
The atomic number is equal to the number of protons
While ethanol being an alcohol does have a direct O−H connection. Hence, ethanol has intermolecular hydrogen bonds. Therefore, more stroger physical bonds have to be destroyed in ethanol, than in acetone. Hence, acetone evaporates faster than ethanol inspite of having higher surface tension.
<h3>What is Vapor pressure ?</h3>
The pressure that a vapour exerts on the condensed phases (solid or liquid) in a closed system when they are in thermodynamic equilibrium with one another is known as vapour pressure (or equilibrium vapour pressure).
- It is significant to remember that when a liquid boils, the pressure of its vapour equals the atmospheric pressure. For instance, the vapour pressure of water when it boils at sea level is 1 atmosphere because the surrounding pressure is also 1 atmosphere.
