How did Democritus contribute to the development of the atom?
matrenka [14]

Democritus developed the atomic model. He theorized that atoms were specific to the material which they composed. He also believed that the atoms different in size and shape, were in constant motion in a void, collided with each other; and during these collisions, could stick together.

"how many fold difference is the hydrogen ion concentration if the ph is 6.7 is increased to 8.7"
Nina [5.8K]

pH of the solution is calculated using the following formula:

pH=-log{[H^{+}]}

Here, [H^{+}] is concentration of hydrogen ion.

Initial value of pH is 6.7, calculate concentration of hydrogen ion from this as follows:

[H^{+}]=10^{-pH}

Putting the value,

[H^{+}]=10^{-6.7}=1.9952\times 10^{-7}

Thus, initial concentration of hydrogen ion is 1.9952\times 10^{-7}.

Now, final pH value is 8.7, calculate concentration of hydrogen ion as follows:

[H^{+}]=10^{-8.7}=1.9952\times 10^{-9}

Thus, final concentration of hydrogen ion is 1.9952\times 10^{-9}.

The ratio of final to initial value will be:

\frac{1.9952\times 10^{-9}}{1.9952\times 10^{-7}}=\frac{1}{100}

Thus, if pH increases from 6.7 to 8.7, concentration of hydrogen ion becomes \frac{1}{100} of the initial value.
