Question

Calculate h30+ for a 8.86*10^3 hbr solution

Answer 1

[H₃O⁺] = 8.86 x 10³ M

Further explanation

The dissociation of water :

H₂O(l)⇒H⁺+OH⁻

Hydrogen ions H⁺ bond with H₂O to form H₃O⁺ ions(hydronium ion)

When acid(Hbr acid) is in the presence of water(dissociates), the H⁺ ions bond with water molecules to form hydronium, the reaction :

HBr(aq)+H₂O→H₃O+(aq)+Br−(aq

So Ionization of HBr :

`\tt HBr\rightarrow H_3O^++Br^-`

[HBr]= 8.86 x 10³,

From equation ratio [H₃O⁺] : HBr = 1 : 1, so

`\tt [H_3O^+]=8.86* 10^3`
