How do you prepare 10mL of a 25M HCl solution?
To prepare 10mL of a 25M HCl solution, you would need to dilute the concentrated HCl solution with the appropriate amount of water. For example, to make a 25M solution, you could start with a 10M HCl solution and dilute it appropriately. To determine the specific volume of each solution needed for dilution, you can use the formula C1V1 = C2V2, where C1 is the initial concentration, V1 is the volume of the initial solution, C2 is the final concentration, and V2 is the final volume.
Why does my .25M solution of zinc sulfate have an orange precipitate?
The orange precipitate in your .25M solution of zinc sulfate may be due to the formation of zinc hydroxide, which can be orange in color. This could occur if the solution pH is high, causing zinc ions to react with hydroxide ions to form the precipitate. It's also possible that impurities or environmental factors could contribute to the color change.
Given a stock solution of 0.5 M NaCl describe how you would prepare 100ml of 2M of the solution of NaCl?
You need to know the gram molecular mass (in this instance, since sodium chloride is an ionically bonded compound and does not have moles in the strictest sense, more properly the gram formula unit mass) of sodium chloride, which is 58.44. The number of grams required may be calculated as set forth below. By definition, a 0.05M solution contains 0.05 moles of solute (sodium chloride in this instance) per liter of solution, and there are 1000 ml per liter. Therefore, the number of moles required for the specified amount of 0.05M solution is 0.05(125/1000) or 0.00625. The amount of sodium chloride required is therefore 0.00625(58.44) or 0.4 grams, to the justified number of significant digits, which is limited by the fact that the molar concentration stated has only one significant digit. If 0.05 were interpreted as having at least three significant digits, then the answer would be 0.3652 grams.
What is the pH of .25M HCl?
The pH of a 0.25 M HCl solution is approximately 0.60. This is because HCl is a strong acid that dissociates completely in water to form H+ ions, resulting in a high concentration of H+ ions and a low pH.
How many grams of NaCl are used to make up 1 liter of a .25M NaCl solution?
To calculate the grams of NaCl needed, you first need to determine the molar mass of NaCl (58.44 g/mol). For a 0.25M solution, you would need 0.25 moles of NaCl in 1 liter (since Molarity = moles/volume). So, you would need 14.61 grams of NaCl (0.25 mol/L * 58.44 g/mol).

Who broke the womans 25m freestyle world record in swimming and what was their time?
You dont swim 25m at a competition. The 25m race is not an official race, as an Olympic pool is 50 meters long.
What percent of 25m is 6m?
percentage = 24%% rate:= 6m/25m * 100%= 0.24 * 100%= 24%
Calculate the durationbetween 6.55 pm and 10.20 pm?
The answer is 3h and 25m. First, cover up the 20m first. If its 55m then you need to have 25m added. Also, 4-1=3 then the answer is 3h 25m.
