PLEASE HELP ME The pH scale for acids and bases ranges from _____.

Chemistry
1 answer:
inysia [295]3 years ago
7 0

The pH scale for acids and bases ranges from 1 - 14. The answer is letter C. The rest of the choices do not answered the question above. There are quite a few relationships between [H+] and [OH−] ions. And because there is a large range of number between 10 to 10-15 M, the pH is used. pH = -log[H+] and pOH = -log[OH−]. In aqueous solutions, [H+ ][OH- ] = 10-14. From here we can derive the values of each concentration.

 


 -log[H+ ] + -log[OH- ] = -log[10-14]


pH + pOH = 14


So pH = 14 – pOH and pOH = 14 –

pH 


It would be B.

Which of these statements is not true about chemical reaction rates?
xeze [42]
Temperature can change a reaction rate because adding or taking away heat means energy is being added or taken away. When energy is added, the particles speed up, so there is a greater chance of the reactants colliding to form the products, which increases the reaction rate. When energy is taken away, the particles more slower, so they don't collide as easily, which slows down the reaction rate.

Therefore, the answer is D.
