Question

1. what is dissociation?
2. what is the chemical formula for water?
3. what is an ion?
4. name the 2 ions form when water dissociates.
5. what is the hydroxide ion?
6. what is a hydrogen ion?
7. what is the hydronium ion and its formula?

acidity or alkalinity is a measure of the relative amount of h+ and oh - ions dissolved in a solution. neutral solutions have an equal number of h+ and oh - ions. acids have more h3o+ ions (h+) than oh - ions. acids taste sour and can be corrosive. digestive fluids in the body are acidic and must be neutralized by buffers. bases contain more oh - ions than h3o+ ions. bases taste bitter and feel slippery.

sodium hydroxide

1. how do you measure for acidity or alkalinity?
2. what is a neutral solution?
3. acids have more ____ ions and taste __. and can be ____.
4. bases contain more ____ ions than ____ ions.

Explanation:

1. Dissociation is the process by which a compound breaks into ions when dissolved in a solvent like water.
2. The chemical formula for water is $H_2O$.
3. An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.
4. When water dissociates, it forms hydrogen ions ($H^+$) and hydroxide ions ($OH^-$).
5. The hydroxide ion is $OH^-$, a poly - atomic ion with a negative charge.
6. A hydrogen ion is $H^+$, which is simply a proton when it is in an aqueous solution.
7. The hydronium ion is $H_3O^+$, formed when a hydrogen ion ($H^+$) combines with a water molecule ($H_2O$).
8. Acidity or alkalinity is measured using the pH scale, which indicates the concentration of hydrogen ions in a solution.
9. A neutral solution has an equal number of $H^+$ and $OH^-$ ions, typically with a pH of 7 at 25°C.
10. Acids have more $H_3O^+$ (or $H^+$) ions and taste sour, and can be corrosive.
11. Bases contain more $OH^-$ ions than $H_3O^+$ ions.

Answer:

1. The process of a compound breaking into ions in a solvent.
2. $H_2O$
3. An atom or molecule with a net electrical charge.
4. Hydrogen ions ($H^+$) and hydroxide ions ($OH^-$)
5. $OH^-$
6. $H^+$
7. $H_3O^+$
8. Using the pH scale.
9. A solution with equal $H^+$ and $OH^-$ ions.
10. $H_3O^+$ (or $H^+$), sour, corrosive
11. $OH^-$, $H_3O^+$
