Assume there is negligible uncertainty in the formula mass of NaOH and in the final volume (2.000 L) and assume random error.arrow_forwardYou are tasked with creating a calibration curve for the absorbance of cobalt solutions of various concentrations. You must prepare 5 standards with concentrations between 1.00 mg/L and 10.0 mg/L Co2+. You have a stock solution with a concentration of 40 mg/L Co2+ and all the standard lab glassware including transfer pipets and flasks. Explain how you would make your 5 standard solutions of various concentrations, including what glassware you would use to measure and prepare each solution.arrow_forward

To test the new method, the researcher purchases a standard reference material sample that is 2.85% iron by mass. Analysis of the iron standard with the new method returns values of 2.75%, 2.89%, 2.77%, 2.81%, and 2.87%. Does the new method produce a result that is significantly different from the standard value at the 95% confidence level?arrow_forward

NBS, peroxide, Aarrow_forwardIn addition to the separation techniques used in this lab (magnetism, evaporation, and filtering), there are other commonly used separation techniques. Some of these techniques are:Distillation – this process is used to separate components that have significantly different boiling points. The solution is heated and the lower boiling point substance is vaporized first. The vapor can be collected and condensed and the component recovered as a pure liquid. If the temperature of the mixture is then raised, the next higher boiling component will come off and be collected. Eventually only non-volatile components will be left in the original solution.Centrifugation – a centrifuge will separate mixtures based on their mass. The mixture is placed in a centrifuge tube which is then spun at a high speed. Heavier components will settle at the bottom of the tube while lighter components will be at the top. This is the technique used to separate red blood cells from blood plasma.Sieving – this is…arrow_forward
