write the full equations and a net ionic equations for both test tubes in the following experiment: put 5 mL of 0.1 M lead nitrate in each of two test tubes. to the first test tube, add 5 mL of 0.1 M sodium oxalate (Na2C2O4) and to the second add 3 mL of dilute sulphuric acid (3 M). Shake to mix. Let the precipitates settle and remove (using a Pasteur pipette) most of the liquid above them. Keep the solid, discard the liquid. Now add 5 mL of dilute nitric acid (3 M) to each test tube and stir with a stirring rod.
Determine the mass of potassium bromide necessary to precipitate all of the Cu^+ in 305 mL solution that is 1.6 M Cu ^+. The ksp of CuBr is 5.3*10^-9
Iminodiacetic acid (IDA) is often used in ion exchange resins as a way to remove heavy metals from industrial waste waters. It forms a 2:1 complex with many heavy metals, with a high selectivity for divalent over monovalent ions. A 22.50 mL sample of 0.0454 M Ni²+ was added to 22.50 mL of 0.190 M iminodiacetic acid (the completely protonated form is abbreviated as H, A*) buffered at pH 7.00. Given that ais 4.6 x 10-3 at pH 7.00, what is the final concentration of Ni²+ remaining in solution? Ni²+ (aq) + 2 A² (aq) = N₁A3(aq) [Ni²+] = K₁ = 2.00 × 10¹4 M

Iminodiacetic acid (IDA) is often used in ion exchange resins as a way to remove heavy metals from industrial waste waters. It forms a 2:1 complex with many heavy metals, with a high selectivity for divalent over monovalent ions. 3 A 27.50 mL sample of 0.0652 M Ni²+ was added to 27.50 mL of 0.195 M iminodiacetic acid (the completely protonated form is abbreviated as H3A+) buffered at pH 7.00. Given that a A²- is 4.6 × 10-³ at pH 7.00, what is the final concentration of Ni²+ remaining in solution? Ni²+(aq) + 2 A²¯(aq) = NIA2¯(aq) Kf = 2.00 × 1014
