Answer:</h3>
The higher the hydronium ion concentration of a solution, the <u>lower</u> its pH.
<h3>
Explanation:</h3>
- The pH is the measure of acidity or alkalinity of a substance.
- We calculate pH by using;
pH = -log[H+]
- The lower the pH of a solution the more acidic it is and the higher the pH the more basic or alkaline it is.
- From this relationship, the higher the hydronium ions concentration of a solution the lower the pH and the more acidic a solution is.
For example,
Solution A with a [H₃O+] of 0.003 M will have a pH of
pH = -log 0.003 M
= 2.52
While, a solution B with a [H₃O+] of 0.025 M will have a pH of
pH = -log 0.25 M
= 1.60
Therefore, the higher the concentration of hydronium ion of a solution the lower its pH is.
Evaporation? I think anyway. Sorry if wrong!
Density=mass/volume. Put the mass (2790g) over the volume (205mL)
Density= 2790g/205mL
Your answer should be in g/mL.
Hope this helped! :)
Scientific Law is proven by the demoonstration of an irrefutable fact - for instance The Law of Gravity.
Legal law refers to the body of man-made statutes passed by mankind in order to govern and control civilization and humanity.
