a "blank" cuvette can be made with a sufficient amount of distilled water (assuming you're diluting your stock solution with distilled water).
The most suitable method for separating a mixture of salt solution and sand to obtain the salt solution is simple filtration. The sand is retained by the filter paper while the salt solution passes through, resulting in the separation of the two components.
sugar is a completely organic solute ant therefor not an electrolite
Equilibrated phenol is phenol that has been mixed with an appropriate buffer solution to maintain a specific pH. This helps to stabilize the phenol solution and make it suitable for various biological applications, such as DNA extraction and purification.
it is very easy to prepare working solution from a stock solution we use the formula for this purpose which is: C1V1 = C2V2 C1 is the concentration of the stock solution V1 required volume from the stock solution C2 concentration of the working solution V2 volume of the working solution
A standard solution of beta carotene can be prepared by dissolving a known quantity of beta carotene in a suitable solvent, such as ethanol or hexane, to make a solution of a specific concentration. The concentration can be verified using spectrophotometric analysis or by comparing the solution color intensity with a standard color scale.
distillation is sometimes suitable for such a task, depending on whats in the solution.

Suitable substances for electrodes in a sodium chloride aqueous solution include platinum, gold, or graphite. These materials are chemically inert and do not react with the electrolyte solution, ensuring accurate measurements during experiments.
Sodium hydroxide (NaOH) is used in this experiment to adjust the pH of the solution to a suitable range for spectrophotometric analysis. It helps stabilize the color of the indicator used and ensures that the absorbance measurements are accurate and reproducible. Additionally, NaOH can help solubilize the solute of interest and prevent any precipitation that may interfere with the analysis.
An ampule is another word for an ampoule, a hermetically-sealed vial containing a sterile solution suitable for injection.
An ampoule is a small glass bottle or container containing a solution suitable for injection.
The most suitable method for separating a mixture of salt solution and sand to obtain the salt solution is simple filtration. The sand is retained by the filter paper while the salt solution passes through, resulting in the separation of the two components.
Titrate each solution separately with solution of known concentration of sodium thiosulphate. The titre value will give the amount of thiosulphate reacted with iodine, hence you can find concentration of iodine.

What is "the nitrogen brown gas" exactly?
An ampule is another word for an ampoule, a hermetically-sealed vial containing a sterile solution suitable for injection.
To standardize an HCl solution with a primary standard Na2CO3 solution, first, prepare a Na2CO3 solution of known concentration. Then, titrate the Na2CO3 solution with the HCl solution using a suitable indicator until the equivalence point is reached. From the volume of HCl solution used and the known concentration of Na2CO3, you can calculate the exact concentration of the HCl solution.
