What will happen after water is added to the salt and sand mixture?
salt becomes dossolved while sand remains as undissolved material at the bottom of container.
Is CuF2 a base acid salt or none?
Solid CuF2 is a salt. However, dissolved in water, it forms Cu2+ and 2 F-, which will form Cu(OH)2+ and 2 HF. However, more of the Cu(OH)2+ remains undissolved, consuming OH- from water and leaving an acidic solution.
What is always true of a weak base?
Some of the original base remains in the solution
What is always true of weak base?
Some of the original base remains in the solution
The minerals which form in a solution from acids and bases are called what?
Its Salt Remains, not just "salt".
What visible evidence indicates that a solution is saturated?
If more solute is added to the solution and the solute remains undissolved, then you know that solution is saturated.
When some of the sugar added to iced tea remains undissolved at the bottom of the glass is the solution saturated?
yes
What is it called when undissolved particles are so?
When some of the material being dissolved remains it's called a saturated solution
Why molarity of a solution remains constant?
Molality of a solution remains constant as mass of a solution independent of temperature.

What remains in solution?
A true solution is monophasic without any residue..
What is the solution that remains after a precipitate has formed?
Supernatant.
Is it true that the pH of a solution remains constant with increasing basicity?
No, it is not true.
If a solution remains unsaturated mineral crystals may precipitate?
true
When a saturated solution is cooled some crystals begin to appear in the solution is the solution now unsaturated?
No, the solution remains saturated. It is just that as the temperatures decreases so does the carrying capacity of the solvent.
