To measure the amount of nickel in some industrial waste fluid, an analytical chemist adds 0.1700M sodium hydroxide (NaOH) solution to a 23.00 g sample ofthe fluid and collects the solid nickel(II) hydroxide (Ni(OH),) product. When no more Ni(OH), is produced, she filters, washes and weighs it, and finds that0.30 g has been produced.The balanced chemical equation for the reaction is:Ni* (aq) + 2N2OH(aq) → Ni(OH),(s) + 2 Na" (aq)O precipitationWhat kind of reaction is this?O acid-baseredoxIf you said this was a precipitation reaction, enter the chemical formula of theprecipitate.If you said this was an acid-base reaction, enter the chemical formula of thereactant that is acting as the base.If you said this was a redox reaction, enter the chemical symbol of the elementthat is oxidized.Calculate the mass percent of Ni in the sample. Be sure your answer has thecorrect number of significant digits.
