Calculate the ph of a solution formed by mixing 200.0 ml of 0.30 m hclo with 300.0 ml of 0.20 m kclo. the ka for hclo is 2.9 × 1
masha68 [24]

Answer:

The pH of the solution will be 7.53.

Explanation:

Dissociation constant of KClO=K_a=2.8\times 10^{-8}

Concentration of acid in 1 l= 0.30 M

Then in 200 ml = 0.30 M\times 0.200 L=0.06 M

The concentration of acid, HClO=[acid]= 0.006 M

Concentration of salt in 1 L = 0.20 M

Then in 300 ml = 0.20 M\times 0.300 L=0.06 M

The concentration of acid, KClO=[salt]= 0.006 M

The pH of the solution will be given by formula :

pH=pK_{a}^o+\log\frac{[salt]}{[acid]}

pH=-\log[2.8\times 10^{-8}]+\frac{[0.06 M]}{[0.06 M]}

The pH of the solution will be 7.53.

Calculate the relative atomic mass of M
aalyn [17]

Answer:

63.55

Explanation:

relative atomic mass=(mass of isotope1×relative abundance)+(mass of isotope 2×relative abundance)/100

r.a.m=(62.93×69.09)+(64.93×30.91)/100

=(4347.8337)+(2006.9863)/100

=6354.82/100

=63.55

When aqueous solutions of lead(II) nitrate and potassium iodide are mixed, what is the formula for the insoluble solid (precipit
andrew-mc [135]

Answer:

The formula for the precipitate is PbI₂

Explanation:

The chemical reaction is:

Pb(NO₃)₂ (aq)  +  2KI (aq)  →  2KNO₃ (aq) + PbI₂ (s)↓

All the iodides, with these cations (Ag⁺, Pb²⁺, Cu⁺, Hg²⁺, Bi⁺³ and Sn⁺⁴) produce insolubles solid.
