Concentration is defined as moles per liter so we convert the mL of water to liters and get. Acids cause burns because they dehydrate the cells they are exposed to. Chem1 Virtual Textbook. Free Hydrogen Ions do not Exist in Water The hydrogen ion in aqueous solution is no more than a proton, a bare nucleus. Reaction The hydronium ion is an important factor when dealing with chemical reactions that occur in aqueous solutions. The red area represents oxygen; this is the area where the electrostatic potential is the highest and the electrons are most dense.
Configuration of Hydronium in Water It is believed that, on average, every hydronium ion is attracted to six water molecules that are not attracted to any other hydronium ions. Problems Determine the pH of a solution that has a hydronium concentration of 2. Determine the hydronium concentration of a solution that has a pH of 1.
If a solution has a hydronium concentration of 3. What is the pH of a solution that has Why do acids cause burns? Answers 1. Hydrogen gas cannot be kept in plastic because it will pass right through the walls of the container. When the Hydrogen atom loses an electron all that is left is a proton.
This is the form of Hydrogen that produces the ATP enzyme that powers our cells and mitochondria. Hydride is a hydrogen atom which has an extra electron. This means that it is a negatively charged ion , or anion. That is why Hydride ion H- has the minus sign distinguishing it from a regular Hydrogen atom H. The two dots after the H means that this ion has two electrons instead of just one. The extra electron means that H- is not a free radical however it is not stable because this form of hydrogen is a very strong base extremely alkaline which reacts with water to produce hydroxide OH — and molecular hydrogen H 2.
Hydride H: — also reacts with metals to form chemical compounds which are reducing agents. Hydroxide OH— is also known as the hydroxyl ion. This reaction is reversible. Add a comment.

For basic solutions it is the reverse. Technetium Technetium 7 7 silver badges 20 20 bronze badges.
Have a look at the duplicate question to see a more in depth answer. M has posted. PM for details. Quote from: ssNake on December 26, , pm. I stand corrected then. Yes, you don't add 'just a proton' to water but since when did we ever have to do that? Quote from: pi on December 26, , pm. Quote from: dc on December 26, , pm. Thanks guys! Just want to clarify this since I'm a bit confused with the different opinions: Quote from: ssNake on December 26, , pm.
