1 L of 0.002 mol/L Pb(NO3)2 has been prepared. Given that ksp for PbCl2 is 1.7 x10^-5, what is the largest number of moles of nacl that can be added to this solution without causing a precipitate to form.

Use equations to explain how a buffer system, such as hno2:no2, reacts with h3o and oh?

A sample of ca(oh)2 is allowed to stand in distilled water until a saturated solution forms. A 50.00 mL sample of this saturated solution is neutralized with 24.4 mL of 0.05 mol/L Hcl 2hcl+ ca(oh)2>cacl2+2h2o Use this information to calculate the ksp for...

What is [H+], [OH-], pH, and pOH for a 0.048mol/L solution of the weak benzoic acid, C6H5COOH?

I don't get it could you explain it with the calculations

All are dispersed from this meeting and all will die in about a week. For not helping others I guess?

K is 4.5 x 10^4 = 45000. Use 0.03 as X

V = sqrt(2 g H)
