After keeping iron nails in a copper sulfate solution for about half an hour, you will observe that the color of the iron nails changes to a reddish-brown due to the deposition of copper on the surface of the nails. The blue color of the copper sulfate solution will fade as copper is transferred from the solution to the nails.
Evaporating the copper sulfate solution to dryness can lead to the formation of copper sulfate anhydrous, which is a white powder, rather than the desired blue crystals of copper sulfate pentahydrate. Keeping some water in the solution helps in obtaining the desired pentahydrate form of copper sulfate with its distinctive blue color.
The control variable in a titration lab is the volume and concentration of the titrant solution being used. Keeping these variables constant ensures that any changes observed in the reaction are due to the titrated solution being analyzed, rather than variations in the titrant solution.
A buffer is a substance in a solution that can absorb excess H+ ions or donate H+ ions to help maintain a stable pH. Buffers are essential for minimizing changes in pH in biological systems and are made up of a weak acid and its conjugate base or a weak base and its conjugate acid.
Yes, dilution involves adding more solvent to a solution, which reduces the concentration of the solute present. By increasing the volume of the solution while keeping the amount of solute constant, the concentration decreases.
To make a solution more concentrated, you can increase the amount of solute (what is being dissolved) in the solvent (what is doing the dissolving) while keeping the volume of the solution constant. This will increase the ratio of solute to solvent, making the solution more concentrated.
Molarity is the no of moles of solute per dm3 solution, the temperature change changes the volume so molarity becomes effected.

Iron is a more active metal than copper, so it replaces/displaces the copper in the copper sulfate, forming iron sulfate and copper. So the hole in the iron pot is where the iron atoms came from. This is called a single replacement/displacement reaction.
When a solution is diluted, additional solvent is added, which increases the total volume of the solution. This dilution process reduces the concentration of the solute in the solution while keeping the amount of solute constant.
A buffer is a substance in a solution that releases and captures hydrogen ions, keeping the pH the same.Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not changeA buffer resists change in pH by accepting hydrogen ions when acids are added to the solution and donating hydrogen ions when bases are added.
Try keeping a positive attitude towards the changes. Consider them the important good changes of your life.

Save will save to the current file with the changes Save as, allows you to save as a different file with the changes while keeping the old version.
the solution is stable because the solutes present in solution do not separate on keeping or do not settle down on keeping. the solution is always homogeneous in nature. ex. if we make sugar solution it does not get separated only by leaving it for sometime.so this is the proof of stability of solution. my name is prashant kumar .i read in dav public school. hope all people will get satisfy with my answer
