In by nickel of determination Experiment 10: Gravimetric Determination of Nickel the gravimetric precipitating as bis (dimethylgloximato)-nickel(II), the effect of mistakably using 10% alcohol for washing the precipitate instead of 30% is: a) Negative error in the weight of the metal-chelate b) Using 50% alcohol precipitated impurities will help decrease the c) Remove the excess dimethylglyoxime Co- d) Washing with 50% alcohol will help to get denser mass for the precipitated chelate making it easier to be filtrated e) Positive error in the weight of the metal- chelate
