Answer:
The object will float on the surface of water if its density is less than the equal volume of water.
Explanation:
Density:
It is define as mass per unit volume.
d=m/v
it is mostly measure in g/mL
it is represented by ρ (rho)
The density of water is one gram per cubic centimeter. If the object is less denser than water it will float. If the density of object is greater than the density of water it will sink.
Other examples:
some rocks are more denser then water so they will sink in it.
density of oil is less than vinegar, so it will float on the surface of vinegar

What is the solubility of water?
- When a solute is dissolved in a solvent to give a homogeneous mixture, one has a solution.
- Solubility is generally expressed as the number of grams of solute in one liter of saturated solution.
- For example, solubility in water might be reported as 12 g/L at 25 oC.
2CuBr + 2OH- ---> Cu2O(s) + 2HBr(aq)
adding OH- to the CuBr also shifts the equilibrium to the right side therefore increasing pH will increase the solubility of the CuBr.
