What is as stock solution?
A stock solution is a highly concentrated solution that is usually diluted in labs to get more precise moralities in experiments.
What is difference between stock and working solution?
A stock solution is a concentrated solution of a substance that is diluted to make working solutions of desired concentrations. A working solution is a solution ready for immediate use in an experiment or process. Stock solutions are typically stored for longer periods and used to prepare multiple working solutions.

What volume of a 2.5 M stock solution of acetic acid (HC2H3O2) is required to prepare?
To prepare 500 mL of a 0.5 M solution of acetic acid, you would need to take 100 mL of the 2.5 M stock solution and dilute it to 500 mL. This is because the molarity equation (M1V1 = M2V2) can be used to calculate the volume of stock solution needed for dilution.
What volume of a 2.5 M stock solution of acetic acid (HCHÀO) is required to prepare 100.0 milliliters of a 0.50 M acetic acid solution?
To prepare a 0.50 M acetic acid solution, you would need to dilute the 2.5 M stock solution. By using the formula M1V1 = M2V2, you can calculate the volume of the stock solution needed as: (0.5 M)(100.0 mL) = (2.5 M)(V2), where V2 is the volume of the stock solution needed. So, V2 = (0.5 M x 100.0 mL) / 2.5 M = 20.0 mL. Therefore, you would need 20.0 mL of the 2.5 M stock solution to prepare the desired 100.0 mL of 0.50 M acetic acid solution.
How do you prepare stock solution Leishman stain?
To prepare a stock solution of Leishman stain, mix the Leishman stain powder with a suitable solvent like methanol or ethanol to make a concentrated solution. Filter the solution to remove any undissolved particles. Store the solution in a dark and cool place, away from light and heat.
What volume of a 2.5M stock solution of acetic acid is required to prepare 100.0 milliliters of a 0.50M acetic acid solution?
To prepare the 0.50M acetic acid solution, you can use the formula C1V1 = C2V2. Plugging in the values, you get (2.5M)(V1) = (0.50M)(100.0mL). Solving for V1 gives V1 = 20.0 mL. Therefore, 20.0 milliliters of the 2.5M stock solution is required to prepare 100.0 milliliters of the 0.50M acetic acid solution.
