write different between hydrogen ion and hudroxil ions
Answers
Answer:
Hydrogen ion concentration is more conveniently expressed as pH, which is the logarithm of the reciprocal of the hydrogen ion concentration in gram moles per liter. Thus, in a neutral solution the hydrogen ion (H+) and the hydroxyl ion (OH−) concentrations are equal, and each is equal to 10−7. A pH of 7 is neutral.
One water molecule gains a hydrogen and therefore takes on a positive charge, while the other water molecule loses a hydrogen atom and therefore becomes negatively charged. H 3O + is called a hydronium ion, and it makes things acidic. OH - is called a hydroxyl ion and it makes things basic.

Hydrogen is the first element in the periodic table of elements. Therefore, it is the smallest atom. It can form either positively charged or negatively charged ions. The key difference between hydrogen atom and hydrogen ion is that the hydrogen atom is neutral whereas hydrogen ion carries a charge.
The hydroxyl ions (OH-) released will combine with any hydrogen ions (H+) in the solution to form water molecules (OH- + H+ = H2O), so we can also define a base as a substance that takes or accepts hydrogen ions (H+) already present in the solution.
Hydrogen forms both H+ ion and H- ion. Explain. Hydrogen can easily lose the only electron present in the valence shell (1s1) and can exist as H+ ion. It can also take up one electron from outside to attain a stable configuration and therefore it exists as H-.
