Generally do all acid solutions contain the H^+ ions?

Answer 1

yes dear that is the main property which makes it an acid otherwise it would not be acid it can be well understood by defination given below


A sour-tasting material (usually in a solution) that dissolves metals and other materials. Technically, a material that produces positive ions in solution. An acid is the opposite of a base and has a pH of 0 to 7. A given amount of an acid added to the same amount of a base neutralizes the base, producing water and a salt. Common vinegar, for example, is a weak solution of acetic acid.What defines acidity or alkalinity? Whether the pH is above (alkaline) or below (acid) a value of 7 (neutral). What defines a value of 7? Having an equal number of H+ and OH- ions, like pure water


examples
HCl,H2SO4 and many other

When the compound HCl is dissolved in water it separates into 2 ions: a positively charged hydrogen proton and a negatively charged chlorine ion. The positively charged hydrogen proton (H+) combines with water and increases the concentration of H3O+ ions, shifting the equilibrium we discussed earlier. Some of these H3O+ ions recombine with the OH- ions, and our sample becomes acidic because it contains more H3O+ ions than OH- ions. The original compound that we added, HCl, is said to be an acid because it donates protons (H+) to the mixture.


HCl------------- ( H+) + (Cl-)

Answer 2

In general an acid is a proton donor (give up a hydrogen ion) but on the otherhand there are such things as Lewis acids.

This was named after the American chemist Gilbert Lewis, can accept a pair of electrons and form a coordinate covalent bond. The Lewis acid and Lewis base theory is one of several acid-base reaction theories, therefore the term acid is ambiguous; it should always be clarified as being a Lewis acid or a Brønsted-Lowry acid.

An electrophile or electron acceptor is a Lewis acid. A Lewis acid usually has a low-energy LUMO, which interacts with the HOMO of the Lewis base. Unlike a Brønsted-Lowry acid, which always transfers a hydrogen ion (H+), a Lewis acid can be any electrophile (including H+). Although all Brønsted-Lowry acids are Lewis acids, in common usage the term Lewis acid is often reserved for those Lewis acids which are not Brønsted-Lowry acids.

Answer 3

You can answer your own question by re-reading the explanation of what an "acid" actually is at the front of whatever chapter you are on. What defines acidity or alkalinity? Whether the pH is above (alkaline) or below (acid) a value of 7 (neutral). What defines a value of 7? Having an equal number of H+ and OH- ions, like pure water...

Answer 4

In 1909, the Danish biochemist Sören Sörensen invented the pH scale for measuring acidity. The pH scale is defined by technique of the formula: pH = -log [H+] note: concentration is often abbreviated by technique of creating use of sq. brackets, subsequently [H+] = hydrogen ion concentration. even as measuring pH, [H+] is in gadgets of moles of H+ in line with liter of answer. link below has pH scale:

Answer 5

Yes. That's what makes it an acid.

Answer 6

yes of course if it didn't it wouldn't be acid
