Question

A solution made bully adding solid Naclo to enough water to make 2.00L of solution has a pH of 10.50 Given that the Ka of Hclo is 3.03e-18 Calculate the number of miles Naclo that were added to the water A solution made bully adding solid Naclo to enough water to make 2.00L of solution has a pH of 10.50 Given that the Ka of Hclo is 3.03e-18 Calculate the number of miles Naclo that were added to the water Given that the Ka of Hclo is 3.03e-18 Calculate the number of miles Naclo that were added to the water

Explanation / Answer

[OH]=x

ka1=10-10.5 =3.16*10-11

[Hclo]=3.03*10-18

ka1=x2 /[3.03*10-18-x}

x2= 3.16*10-11*[3.03*10-18-x}

x2+3.16*10-11x-9.5748*10-29

use general formula

x=(3.16*10-11[+/-]([(3.16*10-11)2]-4[1*9.5748*10-29])(1/2))/2

x=(3.16*10-11+3.16*10-11)/2

x= 3.16*10-11 mol
