MariettaO [177]3 years ago

Streak is the color of the mineral in powdered form. Streak shows true color of the mineral. In large form, trace minerals can change the color appearance of a mineral by reflecting the light in a certain way. Trace miners have little influence on the reflection of the small powdery particles of the streak.

The streak of metallic minerals tends to appear dark because the small particles of the streak absorb the light hitting them. Non-metallic particles tend to reflect most of the light so they appear lighter in color or almost white.

Because streak is a more accurate illustration of the mineral's color, streak is a more reliable property of minerals than color for identification.

To plot the calibration curve, you need to prepare iron solutions with known concentrations and measure their absorbance.
kap26 [50]

To plot the calibration curve, you need to prepare iron solutions with known concentrations and measure their absorbance. You need to pipet 0 mL of the diluted solution to have 0.00 mg of iron.

In spectrophotometry, to plot the calibration curve, you need to prepare solutions with known concentrations and measure their absorbance.

We have a standard iron solution with a concentration of 0.2500g/L of pure iron (C₁). We pipet 25.00mL (V₁) of this standard iron solution into a 500mL (V₂) volumetric flask and dilute up to the mark with distilled water.

We can calculate the concentration of the diluted solution (C₂) using the dilution rule.

C_1 \times V_1 = C_2 \times V_2\\\\C_2 = \frac{C_1 \times V_1}{V_2}  = \frac{0.2500 g/L \times 25.00 mL}{500 mL} = 0.0125 g/L

Then, if we wanted to prepare the blank, that is, the solution that contains the same matrix but not the analyte, and whose concentration in iron is 0.00 mg/L, we wouldn't pipet any of the diluted solution.

To plot the calibration curve, you need to prepare iron solutions with known concentrations and measure their absorbance. You need to pipet 0 mL of the diluted solution to have 0.00 mg of iron.

What visual criterion is to be used to assess whether the crude reaction product is dry prior to semimicro distillation
Olenka [21]

The visual criterion which has to be assessed  is to ensure it's not oily or sticky.

<h3>What is Distillation?</h3>

This is a separation technique that involves the use selective boiling and condensation to separate a liquid mixture into different components.

In the case of Crude reaction product , it is best to ensure that it is not oily or sticky before semimicro distillation is done.
