What laboratory apparatus is used to hold small amount of liquid solution for testing?
A volumetric pipette is most accurate for very small volumes. For 1-10 mL, a volumetric flask can also be used. A graduated cylinder is also used.
See the Related Questions to the left for a complete description of each of these apparatuses.
A micropipet may also be used to accurately measure liquid to the microliter (milionth of a liter)

What amount of NaOH is required to prepare 1N NaOH solution and why only that amount is used?
To prepare a 1N NaOH solution, you would need to dissolve 40 grams of NaOH in water to make 1 liter of solution. This amount is used because 1N solution means 1 mole of NaOH per liter of solution, and the molar mass of NaOH is 40 g/mol, so 40 grams of NaOH is needed to have 1 mole in 1 liter of solution.
How do you prepare NaOH solution in laboratory?
To prepare a NaOH solution in the laboratory, you would first measure out a specific amount of solid NaOH pellets or flakes using a balance. Then, the NaOH is added to a volumetric flask containing a known volume of distilled water until the desired concentration is reached. The solution should be stirred to ensure complete dissolution. Finally, the solution is carefully topped up with more distilled water to reach the final mark on the volumetric flask.
How do you make stock solutions for laboratory experiments?
To make stock solutions for laboratory experiments, you typically measure out a specific amount of a solid or liquid reagent and dissolve it in a known volume of solvent, such as water or another appropriate solvent. This creates a concentrated solution that can be diluted to the desired concentration for use in experiments. It is important to accurately measure and mix the components to ensure the stock solution is consistent and reliable for future use.
How much gram of fecl3 to be used in preparing fecl3 solution for testing citric acid in semen?
The amount of FeCl3 needed depends on the concentration of the FeCl3 solution required for the test. Typically, a 2-5% solution of FeCl3 is used. To make a 100mL of 2-5% FeCl3 solution, you would need to dissolve 2-5 grams of FeCl3 in distilled water. The exact amount can be calculated using the formula: (desired % concentration/100) x volume of solution needed x molar mass of FeCl3.
Solution containing a relatively large amount of solvent?
A dilute solution has a relatively large amount of solvent compared to solute. This results in a low concentration of the solute in the solution. Generally, a dilute solution is one where the proportion of the solute is small in relation to the amount of solvent.
What laboratory apparatus used in heating small amount of solution in experiments?
bunson burner
What are apparatus used as in a laboratory to measure small amount of substances e.g. 1ml of water?

What is the definition of sensitivity and specificity in a dignostic analysis?
Sensitivity in diagnostic laboratory testing represents the smallest amount of substance in a sample that can be accurately measured by an assay. Specificity in a diagnostic laboratory refers to the ability of an assay to measure one particular organism or substance.
What amount of NaOH is required to prepare 1N NaOH solution and why only that amount is used?
To prepare a 1N NaOH solution, you would need to dissolve 40 grams of NaOH in water to make 1 liter of solution. This amount is used because 1N solution means 1 mole of NaOH per liter of solution, and the molar mass of NaOH is 40 g/mol, so 40 grams of NaOH is needed to have 1 mole in 1 liter of solution.
What are the common laboratory apparatus with their classification?

What measuring apparatus that can measure volume and liquid?
A graduated cylinder is a common measuring apparatus used to measure the volume of liquids accurately. It is a tall, narrow container with volume markings along its side to indicate the amount of liquid present.

Why titrate a flask?
Titration is a common laboratory technique used to determine the concentration of a substance in a solution. By carefully adding a titrant (a solution of known concentration) to the solution being analyzed until the reaction reaches an endpoint, the exact amount of substance in the solution can be quantified. Titrating in a flask allows for controlled mixing and easy observation of color changes or other indicators.
How do you make stock solutions for laboratory experiments?
To make stock solutions for laboratory experiments, you typically measure out a specific amount of a solid or liquid reagent and dissolve it in a known volume of solvent, such as water or another appropriate solvent. This creates a concentrated solution that can be diluted to the desired concentration for use in experiments. It is important to accurately measure and mix the components to ensure the stock solution is consistent and reliable for future use.
What indicator tests for sugar?
Benedict's solution test can be used to detect the presence of reducing sugars such as glucose, fructose, and lactose in a solution. Benedict's solution changes color from blue to green, yellow, orange, or red in the presence of reducing sugars, depending on the amount present.
What is a solution that contains a large amount of solute?
The solution has a lower concentration. We can also say that it is dilute. Concentration is the amount of solute over the volume of solvent, thus when a large amount of solvent is used, concentration of the solution is low.
How does the amount of solute moles and grams relate to the density and molarity of the solution?
Increasing the amount of the solute in the solution the molarity and the density of this solution increases.
