What else can I help you with?
What is the mass percent concentration of the solution prepared by adding 20 g of sodium chloride into 380 g of water?
Divide the amount of sodium chloride by the total amount (sodium chloride + water). Then multiply that by 100 to convert to percent.
What is a meaningful sentence using the words dilute solution?
The chemist prepared a dilute solution by adding water to the concentrated solution.
How do you separate lead chloride from a mixture of silver chloride and lead chloride?
Lead chloride can be separated from a mixture of silver chloride and lead chloride by adding water to the mixture. Silver chloride is insoluble in water, whereas lead chloride is soluble. Upon adding water, the silver chloride will precipitate out, leaving behind the lead chloride in solution.
Can be prepared by adding enough amount of soute in a lesser amount of solvent?
hypertonic solution
How do you separate lead nitrate from lead nitrate solution?
You can separate lead nitrate from a lead nitrate solution by adding a soluble salt like sodium chloride, which will cause lead chloride to precipitate out as a solid. The lead chloride can then be filtered out from the solution, leaving you with the lead nitrate solution separated from the lead chloride.
How do you separate lead chloride and silver chloride?
Lead chloride and silver chloride can be separated by adding dilute hydrochloric acid to the mixture, which will dissolve the lead chloride while leaving the silver chloride unaffected. The solution can then be filtered to separate the two compounds. Alternatively, the compounds can be separated by their different solubilities in ammonia solution, where silver chloride dissolves in excess ammonia but lead chloride remains insoluble.
Could you prepare oxalic acid by adding hcl to a solution og sodium oxalate?
Yes, oxalic acid can be prepared by adding hydrochloric acid (HCl) to a solution of sodium oxalate. The reaction that occurs is double displacement reaction where sodium chloride and oxalic acid are formed. Oxalic acid can be obtained by precipitating it out of the solution by adjusting the pH.
How can magnesium hydroxide be separated from the calcium chloride solution?
Magnesium hydroxide can be separated from a calcium chloride solution through precipitation. By adding a strong base, such as sodium hydroxide (NaOH), to the solution, magnesium ions will react to form insoluble magnesium hydroxide, which can be filtered out. The remaining calcium chloride in the solution remains dissolved, allowing for the selective removal of magnesium hydroxide. This process effectively isolates magnesium hydroxide from the calcium chloride solution.
Which compound could be added to an ammonia solution to form a buffer solution?
Ammonium chloride (NH4Cl) could be added to an ammonia solution to form a buffer solution. As ammonia accepts a proton (H+) to form ammonium ion (NH4+), the ammonia-ammonium ion pair acts as a buffer system, maintaining a stable pH.
How would you separate lead chloride from mixture of lead chloride and silver chloride?
One method to separate lead chloride from a mixture of lead chloride and silver chloride is to dissolve the mixture in water, then add hydrochloric acid to precipitate the lead chloride while keeping the silver chloride in solution. The precipitated lead chloride can then be filtered out. Another method is to use selective precipitation by adding a potassium chromate solution, which will form a yellow precipitate with the lead chloride while leaving the silver chloride in solution.
How is sodium chromate prepared?
Sodium chromate is prepared by adding caustic soda to Sodium Dichromate. Go on adding causting soda till the pH drops to 6. what we get is the solution of Sodium chromate and you can evaporate, crystallise and filter.
How do you separate potassium chloride from aqueous potassium chloride?
One way to separate potassium chloride from aqueous potassium chloride is through evaporation. By heating the aqueous solution, the water will evaporate, leaving behind solid potassium chloride. Another method is through precipitation by adding a chemical that reacts with potassium ions to form a solid precipitate of potassium chloride that can then be filtered out from the solution.
