gold density = 19.3 g/cm³
mass = 16.5 kg = 16.5 x 10³ g
volume = 954 ml
gold density based on the experiments:
ρ = 16.5 x 10³ g / 954 ml(cm³) = 17.296 g/cm³ ( not of pure gold)
Answer:
A high pH value indicates a high concentration of OH- ion
Explanation:
The higher the OH- ion concentration high will be the pH.In simple words if the concentration of OH- ions are increased then the pH of the solution will also increase which means the solution will turns towards basic with increasing its OH- ion concentration.
Let us assume that the OH- concentration of a solution is 10-9 so the pOH of that solution will be 9 and the pH will be 5.
Now the concentration of OH-ion of that solution is increased from 10-9 to 10-8 now the pOH of that solution is 8 and the pH is 6.
