If an acid does not show acidic behavior in the absence of water, the definition of acidity under consideration is one that requires positive hydrogen ions and the substance concerned can not produce any such ions in the absence of water, sometimes because they do not contain any hydrogen. This is the common definition of acidity in aqueous solutions. Acidity as defined by G. N. Lewis by loss or gain of electron pairs, however, can occur in the absence of water.
What else can I help you with?
what is the correct order of acidic strength?
The correct order of acidic strength is as follows: strong acids > weak acids > organic acids. Strong acids completely dissociate in water to release H+ ions, making them the most acidic. Weak acids partially dissociate in water, while organic acids generally have a carboxylic acid group and are typically weaker acids.
Is a metal oxide an acid or an alkali?
Metal oxides are basic in nature, not acidic or alkaline. They react with acids to form salts and water, displaying typical basic behavior.
How can one make water acidic?
To make water acidic, one can add an acid such as vinegar or lemon juice. Acids release hydrogen ions when dissolved in water, lowering the pH level and making the water more acidic.
What is the difference between acidic oxide and basic oxide?
Acidic oxides react with water to form acids, while basic oxides react with water to form bases. Acidic oxides have a higher concentration of oxygen ions, leading to a more acidic solution when dissolved in water. Basic oxides have a higher concentration of metal ions, resulting in a more basic solution when dissolved in water.
Why do monoprotic acidic salts behave as strong acids?
Monoprotic acidic salts contain only one acidic hydrogen ion that can easily dissociate in water, leading to a high concentration of H+ ions in solution. This results in a low pH and strong acidic behavior.
Why does dry HCL gas not act like an acid?
Because water is not present. Most of the time the word "acid" means something dissolved in water that produces H3O ions. The "H" of Hcl will not form H3O without water, it is the H3O ions that give acids their charteristic behavior.
what is the correct order of acidic strength?
The correct order of acidic strength is as follows: strong acids > weak acids > organic acids. Strong acids completely dissociate in water to release H+ ions, making them the most acidic. Weak acids partially dissociate in water, while organic acids generally have a carboxylic acid group and are typically weaker acids.
Acidic oxide and water what do they make?
Acidic oxides form (oxy)acids with water: eg. SO2 + H2O --> H2SO3
Is a metal oxide an acid or an alkali?
Metal oxides are basic in nature, not acidic or alkaline. They react with acids to form salts and water, displaying typical basic behavior.
Why do acids do not show acidic behaviour in the absence of water?
Protons (H+, responsible for the acidic behaviour) want to stay near to an anion (the negative part of the acid, eg. Cl-) or (only when present) stick to the partially negative side of a water molecule (the O-side in polar water molecules) Example: HCl + H2O --> Cl- + H+OH2 \_______________/^
Is acids a property of salts?
Some salts dissolved in water have an acidic pH.
How can one make water acidic?
To make water acidic, one can add an acid such as vinegar or lemon juice. Acids release hydrogen ions when dissolved in water, lowering the pH level and making the water more acidic.
What is the difference between acidic oxide and basic oxide?
Acidic oxides react with water to form acids, while basic oxides react with water to form bases. Acidic oxides have a higher concentration of oxygen ions, leading to a more acidic solution when dissolved in water. Basic oxides have a higher concentration of metal ions, resulting in a more basic solution when dissolved in water.
Why water can be classified as both acid and base?
Because water is slightly acidic from all the acids in the air!
Is sulfur oxide acidic?
Yes, both sulfur oxides are acidic: with water the give sulfurous (weak -) and sulfuric (strong -) acids
Classification of oxides?
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.
Why do monoprotic acidic salts behave as strong acids?
Monoprotic acidic salts contain only one acidic hydrogen ion that can easily dissociate in water, leading to a high concentration of H+ ions in solution. This results in a low pH and strong acidic behavior.
