What is the difference between acids and bases and amphoteric salts?

Acids cause solutions to have extra hydrogen ions (H+), bases cause it to have extra hydroxide ions (OH-).
In just regular water, there are always a few broken water molecules floating around, hydrogens missing their electron (H+) and hydrogen-oxygen groups with an extra electron (OH-). Normally these exist in equal amounts, with a concentration each of 10-7 moles per liter. Take -log10(H+) concentration, and you get pH, so neutral water has a pH of 7.
Add an acid to water, such as hydrochloric acid (HCl) to the water, and there will be a surplus of H+ ions, like maybe 100 times as many as before, or 10-5 moles per liter, so now the solution has a pH of 5.
On the other hand, add a little lye (NaOH) and you have a surplus of OH-. Now there might be 100 times fewer hydrogens than there were before, so or 10-9 of them, so now the pH is 9.
In general, salts are ionic compounds that are composed of metallic ions and nonmetallic ions. For example, sodium chloride is composed of metallic sodium ions and nonmetallic chloride ions. Some salts are composed of metallic polyatomic ions and nonmetallic polyatomic ions (ammonium nitrate is composed of ammonium ions and nitrate ions).
Here are some examples for you:
- HNO₃ is an acid. We know this because of the 'H' - NaCl is a salt. It is sodium chloride, the forumla for typical table salt. - Ca(OH)₂ is a base. We know this because of the 'OH'
I know that acids, bases and salts can be a tricky topic to tackle.
Cheers!

Acids are substances that release hydrogen ions in solution, bases are substances that release hydroxide ions in solution, while amphoteric salts can act as both acids and bases depending on the pH of the solution they are in. This means that amphoteric salts can either donate or accept protons, making them versatile in their reactions with acids and bases.

What is amphoteric oxides?
Amphoteric oxides are compounds that can act as both acids and bases, meaning they can react with both acids and bases. These oxides exhibit this behavior depending on the reaction conditions. Examples of amphoteric oxides include zinc oxide and aluminum oxide.
What are the amphoteric elements?
Amphoteric elements are elements that can act as either acids or bases. Common examples include aluminum, zinc, and lead. These elements can form salts both with acids and bases.
What is the word that describe a substance that reacts with both strong acids and strong bases?
Acid and base
Is Caesium oxide amphoteric?
Yes, caesium oxide is a basic oxide, not an amphoteric oxide. It reacts with acids to form salts and water but does not exhibit acidic properties by reacting with bases.
Why statement describes an alternate theory of acids and bases?
The Why statement is a theory that suggests acids and bases react as a result of the difference in electronegativity between hydrogen and oxygen. In this theory, acids donate protons due to the electronegativity difference between hydrogen and oxygen, while bases accept protons. This theory provides an explanation for the behavior of acids and bases in terms of electron movement.
Proteins are what because react as acids or bases?
Amphoteric
What is amphoteric oxides?
Amphoteric oxides are compounds that can act as both acids and bases, meaning they can react with both acids and bases. These oxides exhibit this behavior depending on the reaction conditions. Examples of amphoteric oxides include zinc oxide and aluminum oxide.
Beryllium oxide is amphoteric prove with examples?
Yes, beryllium oxide is amphoteric because can be dissolved by acids and bases..
How Water is an amphoteric substance?
Yes, water can react as an acid or a base - amphoteric.
What are the amphoteric elements?
Amphoteric elements are elements that can act as either acids or bases. Common examples include aluminum, zinc, and lead. These elements can form salts both with acids and bases.
How can you visualize the difference between acids and bases?
no but you can tell the difference by taste
Acids Bases Salts?
Acids are compounds that release hydrogen ions when dissolved in water, bases are substances that release hydroxide ions in water, and salts are compounds formed by the reaction between an acid and a base. Acids have a pH less than 7, bases have a pH greater than 7, and salts are formed through a neutralization reaction.
What is the word that describe a substance that reacts with both strong acids and strong bases?
Acid and base
Is Caesium oxide amphoteric?
Yes, caesium oxide is a basic oxide, not an amphoteric oxide. It reacts with acids to form salts and water but does not exhibit acidic properties by reacting with bases.
1 you expect the hydroxides of metal ions to be soluble in acids What term is used when they are soluble in bases as well?
Amphoteric
Why statement describes an alternate theory of acids and bases?
The Why statement is a theory that suggests acids and bases react as a result of the difference in electronegativity between hydrogen and oxygen. In this theory, acids donate protons due to the electronegativity difference between hydrogen and oxygen, while bases accept protons. This theory provides an explanation for the behavior of acids and bases in terms of electron movement.
Is ammonia an amphoteric substance?
No, ammonia is not an amphoteric substance. Amphoteric substances can act as both acids and bases, while ammonia primarily acts as a base by accepting protons to form ammonium ions.
