How many ml of 1 M stock solution of Na Cl are needed to prepare 200 ml of a 0.05 M solution?
To prepare a 0.05 M solution of NaCl in 200 ml, you would need 2 ml of the 1 M stock solution. This is calculated using the formula: (C1V1) = (C2V2), where C1 is the concentration of the stock solution, V1 is the volume of the stock solution needed, C2 is the desired concentration, and V2 is the final volume of the solution.
How do you prepare 0.5 N NaOH solution?
There is 0.5 moles of NaOH per litre To calculate 0.5 molar NaOH first know the molecular weight of NaOH i.e 40 now multiply the number of moles of NaOH you have (0.5) found as above. so to find the number of grams of NaOH we needed to start with (0.5) * (40) = 20g So dissolve 20g of NaOH in one litre of the solution to prepare 0.5 molar solution
How would you make 100cm3 of 0 01 mol dm3 copper sulfate from a solution of 0 1 mol dm3 copper sulfate?
You would dilute the 0.1 mol/dm3 copper sulfate solution by a factor of 10 to get 0.01 mol/dm3. To make 100 cm3 of this new solution, you would mix 10 cm3 of the 0.1 mol/dm3 solution with 90 cm3 of water.
What pH of 4 is times more acidic as a pH of 7?
As the pH decreases, the solution becomes 10 times more acidic for each point. A solution of pH 4 is 10 times more acidic than a solution of pH 5. A solution of pH 3 is 10 times more acidic than a solution of pH 4. 10 x 10 = 100 A solution of pH 3 is 100 times more acidic than a solution of pH 5.

What is the final concentration of cl- ion when 250 ml of 0.20 M cacl2 solution is mixed with 250 ml of 0.40 M kcl solution?
To find the final concentration of Cl- ions, first calculate the moles of Cl- ions from each solution. Then add the moles of Cl- ions from both solutions and divide by the total volume of the mixed solution (500 ml) to get the final concentration. Using the formula C1V1 = C2V2 where C represents concentration and V represents volume, you can determine the moles of Cl- ions from each solution.
How are volumes of hydrogen peroxide related to concentration of hydrogen peroxide expressed in percentage terms weight volume?
The strength of a solution may be described as a percentage or volume, where 1% hydrogen peroxide releases 3.3 volumes of oxygen during decomposition.Thus, a 3% solution is equivalent to 10 volume and a 6% solution to 20 volume, etc. Answer taken from Wikipedia 19/01/2009
