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.

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.
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.
Acid and base
A substance is amphoteric if it can react as both an acid and a base. To determine if a substance is amphoteric, one can test its ability to react with both acids and bases. If the substance can both donate and accept protons in a chemical reaction, it is considered 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.

Yes, beryllium oxide is amphoteric because can be dissolved by acids and bases..
Yes, water can react as an acid or a base - amphoteric.

no but you can tell the difference by taste
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.
Acid and base
Oxides can be classified into acidic, basic, amphoteric, or neutral based on their chemical reactivity with water. Acidic oxides react with water to form acids, basic oxides react to form bases, amphoteric oxides can act as both acids and bases, while neutral oxides do not react with water to form either acids or bases.
