Why all molecules with protons are not acids?
Assuming the Brønsted-Lowry definition of acids and bases, an acid is a molecule that donates a proton. While all atoms -- and therefore all molecules -- contain protons, not all are capable of donating them. Those that cannot donate a proton are not considered an acid under this terminology.
What donates H plus ions to solutions?
According to Bronsted-Lowry theory, anything that donates H+ (or protons) atoms to a solution is an ACID. Hence this defines an acid as a proton donor and a base as a proton acceptor.
Why alcohol act as acid or base in some different reactions?
Ethanol (C2H5OH) can, partially and VERY WEAKLY, either accept or donate protons: from a strong acid and to a strong base respectively in the same way water does, this is called ampholytic behaviour.
What kind of solution do all the molecules of an acid break apart in water?
When an acid dissolves in water, the molecules of the acid break apart into ions. Specifically, the acid molecules donate protons (H+ ions) to the water molecules, resulting in the formation of hydronium ions (H3O+) and negatively charged ions from the acid. This process is called ionization or dissociation.
What makes molecule less basic?
A molecule becomes less basic when it gains or loses a proton. This can happen through the addition of a strong acid or the removal of a strong base. Additionally, molecules with electronegative substituents or electron-withdrawing groups tend to be less basic as they have a reduced ability to donate electrons and accept protons.
What is the basictiy of nitric acid?
The basicity of an acid is equivalent to the number of protons that one molecule can donate. A nitric acid molecule can only donate one proton. Therefore, it has the basicity of one.
What is meant when an acid is referred to monoprotic diprotic or triprotic?
monoprotic- an acid that can donate only 1 proton to a base diprotic- an acid that has two ionizable hydrogen atoms in each molecule, such as sulfuric acid
What does Monoacid mean?
An acid is a substance that releases hydrogen ions in water or will donate a hydrogen ion to another molecule. A monoacid, or monoprotic acid, is an acid that can only donate one hydrogen atom per molecule. You can also have diprotic acids, such as sulfuric acid, which can donate two hydrogen ions, and triprotic acids such as phosphoric acid, which can donate three.

Carbonic acid is a diprotic acid explain what that means?
di means 2 and so it means that this acid contains 2 protons that it can give up or donate during a rxn
Examples of the acids which are dibasic?
Sulfuric acid (H2SO4), phosphoric acid (H3PO4), and carbonic acid (H2CO3) are examples of dibasic acids. These acids have two ionizable hydrogen atoms, meaning they can donate two protons per molecule when dissolved in water.
Why is phosphoric acid called a triprotic acid?
because it has three protons

What is electron donor?
A proton donor is a molecule that donates it's protons to other molecules.
How is a weak acid diffrent from a dilute acid?
A weak acid will not donate all of its protons during dissociation. A dilute acid is simple any kind of acid with water added to disperse the acidic molecules and bring the pH closer to 7.
CH4 acid or base?
Arrhenius acids are ones that give up protons when dissolved in water. Methane is a non-polar molecule which means it is insoluble in water and, therefore, is not an Arrhenius acid. It cannot be described as a Lewis acid or base either because it doesn't donate protons or an electron pair nor does it receive them.
