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.

It is in an incorrect spot i think
It will be a. <span>benzene.</span>
The reaction formula of this is C3H8 + 5O2 --> 3CO2 + 4H2O. The ratio of mole number of C3H8 and O2 is 1:5. 0.025g equals to 0.025/44.1=0.00057 mole. So the mass of O2 is 0.00057*5*32=0.0912 g.
