Advantages of calcuylations determoine nickel concentration using edta

how to measure the nickel ion concentration in solutionindustry. depends on the concentration of nichel; if it is a galvanic solution nickel bath you are in the range of g/l and you can operate a ni titration with edta the procedure is very simple14a. complexometric determination of nickeldetermination of nickel using edta titrant is carried in alkaline environment. it is better if the environment is slightly alkaline at the beginning of reaction, and becomes more alkaline (from ammonia added). indicator is murexide, changing color from yellow to violet.how do you calculate the concentration of edta innov 24, 2013· nov 24, 2013· 1.012x10^5 mol edta (25.00ml)= 2.531 x 10^4 mol of edta. this is the amount of moles in the new solution. now we need to find the amount of moles per liter of the specific concentration of edtacomplexometric determination of nickel using edta, sampleintroduction the aim of the experiment is to determine the percentage of nickel salt using a complexometric technique. ethylenediaminetetraacetic acid (edta) is a hexadentate ligand which forms stable complexes with most metal ions, thus is widely used to determine metals inedta titrations 1 standardization of edta and analysis ofthe mean corrected titration volume of the edta solution was 16.25 ml (0.01625 l). the reaction between edta and all metal ions is 1 mol to 1 mollculate the molarity of the edta solution. state the value to 5 places after the decimal point. answer mol arity edta (m ol / l) = volume zinc ( l)× mol rity m l / × 1 mol edta 1 mol zinc × 1edta titration calculationsconcentration of ca2+ ions is usually expressed as ppm caco 3 in the water sample. this is equivalent to 1 gram of caco 3 in 10 6 grams of sample. in the lab 1 ppm caco 3 is expressed as 1 mg caco 3 per 1 liter of sample or ppm is mg caco 3 per l of sample. calcium ions can be analyzed by titration with edta using an appropriate indicator.determination of nickel by direct titration withuse the procedure under copper or calcium to standardize the edta. nickel metal takes time to dissolve. if in doubt check with dr. sherren. edta preparation prepare 200 ml. of standard 0.05 m edta (disodium ethylenediaminetetraacetate) solution. use the edta as it is in the bottle.
