To measure the amount of nickel in some industrial waste fluid, an analytical chemist adds 0.460 M sodium hydroxide (NaOH) solution to a 23.0 g sample of the fluid and collects the solid nickel II) hydroxide (Ni(OH)2) product. When no more Ni (OH) is produced, he filters, washes and weighs it, and finds that 206. mg has been produced The balanced chemical equation for the reaction is: Ni2+(aq) + 2NaOH(aq) Ni (OH)2(s) + 2Na+ (aq) ■ precipitation x 10 acid-base...
1. Balance the reaction below and determine how many grams of nickel(II) phosphate will be formed when sodium phosphate (12.05g) is mixed with nickel(II) nitrate (175 mL, 0.500 M). After the reaction is complete, what is the concentration of the unprecipitated ion (either PO or Ni2+). Na PO, + Ni(NO3)2 — Ni,(PO3)2+ + NaNO,
NICKEL (II) The reaction with DMG gives: [Ni(DMG)212 (aq) The reaction with HCl gives: [NiClg(aq) The reaction with ethylenediamine gives: [Ni(en)al2(aq) The reaction with NaOH gives: Ni(OH)2(s) The reaction with EDTA gives: [NIEDTA]2(ag) Write a balanced equation for each reaction. How many d electrons are there in Ni2* For each complex ion formed, indicate the coordination number of the copper atom. Name each complex.

Determine whether a precipitate form in the following reaction conditions: a. A solution containing lead (II) nitrate is mixed with one containing sodium bromide to form a solution that is 0.0150 M in Pb(NO3)2 and 0.00350 M in NaBr. Does a precipitate form in the newly mixed solution? Ksp PbBr2 = 4.67 x 10-6 . b. A solution containing iron (II) nitrate is mixed with one containing sodium phosphate to form a solution that is 0.0365 M in Fe(NO3)2 and...
10.0 g of alloy containing only Fe, Cr and Ni when heated with dil. HNO3 dissolved to give Fe3+, Cr3+ and Ni2+ respectively. The resulting solution was diluted to a total volume of 250.00 cm3 by adding distilled water. 25.00cm3 of the diluted solution was treated with excess NaOH and H2 O2 . The obtained precipitate P was fltered and yellow colour fltrate Q was acidifed with dil. H2 SO4 acid, and titrated with 1.0mol dm-3 Fe2+ solution. The volume...
