Answer:
Take the -logarithm of the concentration of hydrogen ions that are in the solution:
pH=−log(1×10−8M)=8.❤
<span>The symbol for hydronium ion concentration is H+. </span><span>There are quite a few
relationships between [H+] and [OH−]
ions. And because there is a large range of number between 10 to 10</span><span>-15</span><span>
M, the pH is used. pH = -log[H+] and pOH = -log[OH−]. In aqueous solutions, </span><span>[H+
][OH- ] = 10-14. From here we can derive the values of each concentration.</span>
Answer:
The more optically dense that a material is, the slower that a wave will move through the material. ... So as the index of refraction value increases, the optical density increases, and the speed of light in that material decreases.
