From the calculation of the concentration of dissolved substances in preparations. When the left-hand quarter is to prepare sodium hydroxide is as close to the standard concentration of the substance. It reviewed the trial preparation process quite well.
Calculated concentration of solution preparation. When applied to the tri-nitrates. Sodium hydroxide It was close to the concentration of the standards. It was concluded that the experimental results. Step in the preparation was quite good.
Calculation for the concentration of the solution prepared when the triple Australian friends with sodium hydroxide. Is similar to the concentration of standard, so conclusion that step in preparing the matter quite well.
