What is the molarity of a solution that contains 0.5 moles of NaOH in 200ml water?
It is 2.5 molar. The reason for this is that molarity means moles per litre. You have to multiply by 5 to get from 200ml to a litre, so you have to do the same with the moles.
Prepare 5 M NaOH of pH 12?
To prepare a 5 M NaOH solution, measure out 200 g of NaOH pellets and dissolve them in enough water to make 1 liter of solution. To adjust the pH to 12, you can titrate the solution with a standard acid solution (e.g. HCl) until the desired pH is reached. Remember to wear appropriate safety gear and use a fume hood when working with NaOH.
How we can prepare 50 percent NaOH solution?
You must know the method and not just the answer. Think about this problem: What does 5% mean? It tells you that for every 100g (or ml) water, you must have 5g of NaOH. You have 235 ml water. Therefore you will have to use more NaOH. You can calculate this as follows: (235/100)*5= 11.75g NaOH
How many grams of of NaOH are required to prepare 200 mL of a 0.450 M solution?
Approximately 4.50 grams of NaOH are required to prepare 200 mL of a 0.450 M solution. This can be calculated using the formula: moles = Molarity x Volume (in L), and then converting moles to grams using the molar mass of NaOH.
How many grams of NaOH are in 750 ml 0.600 M NaOH solution?
This solution contain 26,3 g NaOH.
How do you prepare 30 percent of NaOH?
To prepare a 30% NaOH solution, you would mix 30 grams of NaOH with enough water to make 100 grams of final solution. Be sure to use caution when handling NaOH as it is a caustic substance and can cause skin and eye irritation.
How do you prepare 1 N to 0.1N NaOH solution?
To prepare 0.1N NaOH solution from a 1N NaOH solution, you can dilute 1 part of the 1N solution with 9 parts of water (since 1/10 = 0.1). Measure 1 volume of the 1N NaOH solution and add 9 volumes of water to it, then mix well to get your 0.1N NaOH solution.
How an exact of 0.1N solution of NaOH can be prepared?
To prepare a 0.1N solution of NaOH, dissolve 4g of NaOH pellets in enough distilled water to make 1 liter of solution. This will result in a solution with a concentration of 0.1N of NaOH.
How do you prepare a 50 percent of NaOH solution?
To prepare a 50% NaOH solution, dissolve 50g of NaOH pellets in 50mL of distilled water. Slowly add more water while stirring until you reach the desired volume. Make sure to wear appropriate protective gear and handle NaOH with care due to its caustic nature.
How can we Prepare 1mM NaOH?
To prepare 1 mM NaOH solution, you would dissolve 0.040 g of NaOH in enough water to make 1 liter of solution. This concentration is equivalent to 1 millimole of NaOH per liter of solution. Be cautious when handling NaOH as it is a caustic 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.
How you prepare 0.02M NaOH solution?
To prepare a 0.02M NaOH solution, weigh out 0.08g of NaOH (based on its molecular weight) and dissolve it in enough water to make 1 liter of solution. Remember to wear appropriate safety gear like gloves and goggles when handling NaOH due to its caustic nature.
HOW TO 0.1N NaOH solution preparation?
To prepare a 0.1N NaOH solution, dissolve 4g of sodium hydroxide (NaOH) pellets in enough water to make 1 liter of solution. Use a volumetric flask to accurately measure the final volume. Remember to handle NaOH with caution as it is a caustic substance.
What is the molarity of a solution that contains 0.5 moles of NaOH in 200ml water?
It is 2.5 molar. The reason for this is that molarity means moles per litre. You have to multiply by 5 to get from 200ml to a litre, so you have to do the same with the moles.
How do you prepare 10 N of NAOH?
To prepare a 10 N solution of NaOH, you would dissolve 400 g of NaOH pellets in enough distilled water to make 1 liter of solution. Remember to add the NaOH to the water slowly and carefully due to the exothermic nature of the reaction. Finally, stir the solution until all of the NaOH has fully dissolved.
How do you prepare a 6N NaOH solution from a 10N NAOH solution?
To prepare a 6N NaOH solution from a 10N NaOH solution, you would dilute the 10N solution by adding water. Use the dilution formula: C1V1 = C2V2, where C1 is the initial concentration (10N), V1 is the volume of stock solution needed, C2 is the final concentration (6N), and V2 is the final volume of the solution you want to make. Calculate the volume of the 10N solution needed and add water to reach the final desired volume for a 6N NaOH solution.
How to prepare 2N solution of NaOH in 10 ml of water?
To prepare a 2N solution of NaOH in 10 ml of water, you would need to calculate the amount of NaOH needed based on its molecular weight. Once you have determined the amount needed, dissolve it in 10 ml of water to make the solution. Remember to handle NaOH with caution as it is corrosive.
