The concentration of pb2+ in a solution saturated with pbbr2(s) is 2.14 ✕ 10-2 m. calculate ksp for pbbr2.
Ugo [173]
Concentration = 2.14 âś• 10-2 m 
For [Br-], there are 2 ions so 2 x 2.14 x 10^-2 =4.28 x 10^-2  
Ksp = [Pb][Br]^2 = 2.14 âś• 10-2 x (4.28 x 10^-2 )^2 = 39.20 x 10^-6 
Ksp = 3.92 x 10^-5

Determine the volume of 0.150 M NaOH solution required to neutralize 145 mL of a 0.25 M HCl solution. The neutralization reactio
QveST [7]

Answer:-

241.66 mL

Explanation:-

Volume of HCl = 145 mL / 1000 = 0.145 L

Strength of HCl = 0.25 M

Number of moles of HCl = Strength x volume

= 0.25 M x 0.145 L

= 0.03625 moles

According to the balanced chemical equation

NaOH(aq) + HCl(aq) → H 2 O(l) + NaCl(aq)

1 mol of HCl reacts with 1 mol of NaOH.

∴0.03625 moles of HCl reacts with 0.03625 moles of NaOH.

Strength of NaOH = 0.15 M

Volume of NaOH = Number of moles / strength

= 0.03625 moles / 0.15 M

= 0.24166 L x 1000

= 241.66 mL
