How to calculate hydrogen ion concentation from pH

pH - (log) [H+]

Explanation:

Find the Hydrogen ion concentration;

then the logarithm of that concentration, and change the sign.

If [H+] = 1 x /10 to the negative 7 (moles per liter), the log of that is -7, the opposite of that is 7

Ergo, pH 7. IF the acid is very very concentrated, the pH can be negative. This was a very easy one I chose that you likely saw in class, but work on a few more, and it will be easy. When the acids are very very weak disassociation, you will need another, little bit harder equation. Just remember what pH is; “the opposite of the log of hydrogen (or Hydronium ion) concentration.

the answer is the first option

explanation:

just googled it m8. not that hard

lol

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
