Why The blue CuSO4 solution turn to a still deeper blue When NH3 is added?

The light blue color of a solution of CuSO4 in water is due to absorption of yellow light by a coordination complex of water and copper cations. When NH3 is added, the water molecules in the coordination complex are replaced by ammonia molecules, and the resulting complex absorbs yellow light more strongly than the original one.

A strip of magnesium metal into a solution of copper sulfate?
When we did it the other day what happened was this: the magnesium caused tiny bubbles and little dots of black fell to the bottom of the test tube (Copper I guess). When the reaction stopped, the liquid was still blue. We tried heating the mixture and got a bit more bubbles and 'dots' then we left the test tube for several days. Now the magnesium is coated with a pretty turquise coating of something, the solution is still blue, the dots are still black at the bottom of the tube. So CuSO4 + H2O + Mg should give you MgSO4 (which is soluble) and Cu. I do not know what we have actually got. The chemicals came from a chemistry set...the CaOH was equally not 'right' or rather it was far less 'basic' that I expected hmmm.
What happens when a drop remains hanging from the tip of the burette after the solution has been added to the flask?
If there are any drops still hanging on the burette, they should be washed into the flask with distilled water.
Why does a solution of a conjugate acid base pair behave as a buffered solution?
The resist pH change in the following way: If you add a strong acid to the buffer solution, the conjugate base gets protonated, but the pH is not significantly changed. If you add a strong base to the buffer, the conjugate acid gets deprotonated, and again the pH is not changed very much. If you only had one component (let's say just the conjugate base), then it would not be able to resist change in pH if you added a strong base to the solution (although it would still counteract the affect of added acid).
What is the reaction between copper sulfate and sulfuric acid?
CuSO4 + H2SO4= no reactionCopper is below hydrogen in the metal activity series, meaning it doesn't normally displace hydrogen from acids (it can react to some degree with some acids).Perhaps more to the point: if it did displace the hydrogen, you'd still have H2SO4 and CuSO4. If the products are the same as the reactants, there can't be a reaction.
A solute and a solvent that do not separate is a?
it is a solution, seeing as they are still one chemical. if you mis a solute with a solvent you get a solution.
When was Deeper Still created?
Deeper Still was created in 2002.

When you add baking soda to vinegar the mixture fizzes as carbon dioxide is produced Suppose you added water to the vinegar before you mixed it with the baking soda what do you think will happen?
It will still fizz, but fizz less the more water is added to the vinegar (acid) solution. Vinegar is already a diluted solution of acetic acid, and is mostly water.
What is the quote of Corrie Ten Boom's about God's love being deeper than the pit?
No pit is so deep that the love of God is not deeper still.
Does frost go deeper when the temp warms?
It might. It depends on what the average temperature is. If it is warmer but still below freezing, then frost can continue to go deeper. Warm temperatures do not CAUSE frost to go deeper though.
What happens when a drop remains hanging from the tip of the burette after the solution has been added to the flask?
If there are any drops still hanging on the burette, they should be washed into the flask with distilled water.
How can you tell when a Solution saturated?
No more solute can be dissolved in the solvent. If you have ever added a lot of sugar to a drink, you would find that no matter how much you stirred, there would still be undissolved sugar at the bottom of the glass. The drink is a saturated solution- no more sugar will dissolve in it.
