Water Stuff! By Brienna.   (V2 because I didn’t press submit.)

1. Water can ionize itself!
2. Water can make other things besides H2O, it can also make H3O, which is hydronium, and OH-, which is hydroxide.
3. There’s a lot of math. 😭😭😭 But, moles (ml) are the unit of measurement that we use in this area.

Q: what if the ph of water is like… 7.6? Does that mean that drinking it can cause issues? And what do you do if you DO drink let’s say a cup or two of ph 7.8 water? What could happen?

# data[].attributes.body
The auto ionization of water is a big phenomenon

1) I learned how H2O can ionize itself, becoming hydroxide and hydronium

2) it’s only found in 1/560,000…….. (a really big number)

3) the concentration of H3O in typical water is [1x10^-7 M

Since acids and bases react with each other, what causes water to autoionize itself ?

# data[].attributes.body
1) Water can ionize itself to become hydronic and hydroxide.
2) The equal concentration of both ions coincides with water’s neutrality.
3) In autoionization , the hydrogen leaves its electron with the first molecule, making the hydrogen positively charged.

Why does autonization happen? What causes the process?

# data[].attributes.body
1. it is possible for water molecules, under the right conditions, to turn into molecules which have 3 hydrogen atoms bonded to 1 oxygen or only 1 hydrogen atom bonded to 1 oxygen. this change is called the autoionization of water.

2. the changes that are mentioned above result in charged ions, called hydronium (h3o+) and hydroxide (oh-), respectively.

3. hydronium is extremely uncommon and is not usually found in large quantities within normal water. it is so uncommon that it is only found in 1/560,000,000 molecules of normal water.

question: is there a reason why autoionization of water does not occur more frequently? is it because the water molecule (h2o) is very stable on its own?

# data[].attributes.body
1.  A typical hydrogen atom is just a protrom in the nucleus and an election orbiting around it.

2. A liter of water contains 56 moles of H2O.

3. The concentration of H3o is 1 times 10 to the negative 7 molar.

Question - How do we find the autoionization of water? Also is it possible to find the autoionzation of other liquids as well?

# data[].attributes.body
Things I learned
1. How the equilibrium position will always be to the left because it favors being two H20 molecules instead of H3O+ and -OH ions.
2. How in 1 liter of what it contains an approximate 56 moles of water.
3. That hydronium and hydroxide coming together means Auto ionization. Meaning one molecule will take a postive and the other a negative.

Question: Does an external High Voltage draw the ions to the side of a container??

# data[].attributes.body
3 things I've learned
1. something I learned from this was the hydronium ion which is a cation that is a positively charged ion and the hydroxide ion that's an anion which is a negatively charged ion.
2. I learned that a mole is = 6.02x10^23
3. the last thing I learned was that one L of water has 56 moles of H2O in it.
Q.Does an external High Voltage draw the ions to the side?

Requires approval

Three things I learned:
1. Electrons from the water molecule nabs one hydrogen, though not  the entire hydrogen(which consists of a nucleus and electron) but just the proton of the hydrogen.
2. In a liter of Water, there are 56 moles of H2O
3. The concentration of H30 does not happen frequently as H20
One question I have is, when the video mentions that autoionization happens under the right circumstances, what is this right circumstances that is being talked about?

-A liter of h2o contains 56 moles of h2o

-Hydronium ions in water depends on its concentration

-The equilibrium of the ionization of water is more to the left (signaling favor to the molecules of h2o)
-why does such a different molecule still able to act like water?

# data[].attributes.body
1. I learned that auto ionization will not happen all the time, it has to be during the right conditions.
2. I learned that if auto ionization does happen, one molecule of water will take the proton from the covalent bond, and the other will take both electrons, thus one has a net positive charge, and the other a negative charge.
3. I learned that the ratio for hydronium molecule to water, is one hydronium molecule to roughly 560,000,000 molecules of water
Q: Does anything else happen to the hydroxide molecule, other than having a negative charge?

# data[].attributes.body
3 things I learned:
1. Hydronium Ion is H3O (cation)
2. Hydroxide ion is OH- (anion)
3. The autoionization of water is the reaction of water molecules to form two ions.

A question I still have:
If there is autoionization of water, is there a reverse reaction?

# data[].attributes.body
1. I learned what a "hydronium ion" looks like
(H3O+)
2. Learned more about how autoionization
works
3. I learned that a mole is a quantity

Q: How do electrons get "swiped"?
