It's the hydrogen ion: H+
The answer above is only partly true. First of all, in any aqueous solution, it is hydronium, H3O+, and not the hydrogen ion that is found. Secondly, this answer assumes the Arrhenius definition (or Bronstead-Lowry definition) of acids. The most general definition of acids is the Lewis definition, which states that acids are electron acceptors. This has nothing to do with hydrogen or hydronium, and using this definition, an acidic substance may not have any H+ or H3O+ present. Using the Lewis definition, there is no common constituent in acid solutions in fact!
What else can I help you with?
Is acidic soluble in water?
A solution can only be acidic if it is aqueous as H3O+ ions cause acid properties. All acid solutions are by definition soluble in water.
Does acid solutions have a pH above 7?
yes all acids have pH below 7 as SUSTANCES HAVING Ph below 7 are acids and that having pH up 7 are bases
All dilute basic solutions are weak bases?
Not all dilute basic solutions are weak bases. Dilute solutions can still contain strong bases like sodium hydroxide, which dissociates completely in water to form hydroxide ions. This makes it a strong base, even in dilute solutions.
Why don't all acids turn indicators pink?
Not all acids turn indicators pink because the color change of an indicator depends on the pH of the acid. Different indicators have different color changes at different pH levels. Some indicators change color in acidic solutions, while others change in basic solutions.
Which amino acid is most common in all three animals?
The amino acid that is most common in all three animals (humans, dogs, and birds) is glycine. Glycine is the simplest amino acid with a hydrogen atom as its side chain, making it a versatile component of proteins.
Which ion is present in all acid solutions?
Hydrogen
What do all solutions have in common?
they all have a product.........
What liquid will rust steel?
all acid solutions and most salt solutions and water in most formats
What is the pH or neural solutions?
0 acid all alcoholine solution
Are all acid solutions strong electrolytes?
Not all acid solutions are strong electrolytes. Strong acids, such as hydrochloric acid, sulfuric acid, and nitric acid, completely dissociate into ions in solution, leading to strong electrical conductivity. Weak acids, such as acetic acid, only partially dissociate, resulting in a lower concentration of ions and weaker electrical conductivity.
Is an acid soluble in water?
A solution can only be acidic if it is aqueous as H3O+ ions cause acid properties. All acid solutions are by definition soluble in water.
WHAT ELEMENT IS COMMON TO ALL ACID?
hydrogen
What do all liquid solutions have in common?
They all contain a solvent and a solute (or more solutes).
Name of gas which is the main constituent of acid rain?
Carbon Dioxide is always in the atmosphere, so all rain has some carbonic acid in it.
