What is the conjugate acid of clo3 −? 1. hclo3 2. clo3 − does not contain oh−, so it is not a base and thus cannot have a conjug
Alla [95]
Answer is: 1. HClO₃; (chloric acid).
Balance chemical reaction (dissociation):
ClO₃⁻(aq) + H₂O(l) ⇄ HClO₃(aq) + OH⁻(aq).
According to  Bronsted-Lowry theory acid are donor of protons and bases are acceptors of protons (the hydrogen cation or H⁺).
The chlorate anion (ClO₃⁻) is Bronsted base and it can accept proton and become conjugate acid HClO₃..

The equilibrium constant (kp) for the interconversion of pcl5 and pcl3 is 0.0121: pcl5 (g) ⇌ pcl3 (g) cl2 (g) a vessel is charge
Aleonysh [2.5K]
Let's assume that change of pressure of PCl₅ is X

According to the ICE table,
                               PCl₅(g) ⇄ PCl₃(g) + Cl₂(g)
Initial Pressure       0.123           -             -
Change                   -X               +X          +X
Equilibrium             0.123 - X       X           X

       Kp = Ppcl₃(g) x Pcl₂(g) / Ppcl₅(g)
by substitution,
0.0121 = X × X / (0.123 - X)
0.0121 × (0.123 - X) = X²
1.4883 × 10⁻³ - 0.0121X = X²
X² + 0.0121X - 1.4883 × 10⁻³  = 0
X₁ = 0.03735 or X₂ = -0.03865
X cannot be a negative value since X is a pressure.
Hence,
   X = 0.03735 atm

Hence, partial pressure of PCl₃ is 0.03735 atm
