Best Answer

Acids are proton donors. Since protons are H+ ions, an acid must have a proton to give away.

What part of an acids chemical formula is responsible for its acidic properties?

Hydrogen ions give acids their acidic properties.


Do acidic solutions give some or many hydrogen ions?

The more acidic a solution is, the more hydrogen ions it gives off.


What acid responsible for the sour taste of grapefruit lemons and oranges is?

lemon & oranges are acidic in nature b/c when they dissolve in water they give hydrogen ion


Which acidic gas reacts with water to give two acids?

co2


Acids give off what ions?

acids give off H+ ions


What makes acids weaker than other acids?

The strength of an acid is determined by how easily they give up their hydrogen ion, if they give it up easily they are strong acids, if they release the hydrogen ion slowly they are weak.


Is sulfur oxide acidic?

Yes, both sulfur oxides are acidic: with water the give sulfurous (weak -) and sulfuric (strong -) acids


Is an acid is any compound that forms H plus ions in solution true?

Not all the time. Only acids that react with metals will give of Hydrogen (H) Acid + Metal --> Salt + Hydrogen


How halogen acids can be arranged in their increasing order of acidic character or strength?

1. please think about focusing on an English class in the future. 2. you would need to find the hydrogen concentration of your solution since solutions come in all different concentrations. then take the -log of your hydrogen concentration. that will give you the pH. solutions with a lower pH are more acidic. i.e. HCl (hydrochloric acid) is a strong acid. say we have .1 mole of it. since strong acids do not dissociate that is your concentration. the -log(.1) is 1. a one molar solution of HCl has a pH of 1. all halogen acids are strong except for HF (hydrofluoric acid). it is a weak acid due to its electronegativity difference to hydrogen.


Does zinc reacts with the acid?

Yes it does. It is a reactive metal and displaces hydrogen from the acids to give a zinc salt and hydrogen gas.


Doeds acid and metal react to give off oxygen?

NO!!!! The general chemical reaction for acids and metals. is Acid + Metal = Salt + Hydrogen (NOT Oxygen). e.g. 2HCl + Zn = ZnCl2 + H2


What substances give up hydrogen ions when dissolved in water?

Acids. They dissociate in water/aqueous solutions to from hydrogen ions (and the corresponding anion).
