Calculate the molar concentration of oh− ions in a 0.555 m solution of hypobromite ion (bro−; kb=4.0×10−6).

The molar concentration of OH⁻ ions in a 0.555 M solution of hypobromite ion is 1.5 × 10⁻³ M.

A Bronsted-Lowry base is a species that accepts H⁺.

Let's consider the basic reaction for hypobromite ion.

BrO⁻ + H₂O ⇄ HBrO + OH⁻

Since BrO⁻ is a weak base, we can calculate the concentration of OH⁻ using the following expression.

[OH⁻] = √(Kb × Cb)

[OH⁻] = √(4.0 × 10⁻⁶ × 0.555) = 1.5 × 10⁻³ M

where,

The molar concentration of OH⁻ ions in a 0.555 M solution of hypobromite ion is 1.5 × 10⁻³ M.

i think it is true since you can test the answer and can use observations to complete it.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
