Is cacl2 acidic or basic?
Answer and Explanation: Calcium chloride is neither acidic nor basic.
If you consider the chloride ion to be the conjugate base of HCl (according to Bronsted-Lowry rules), then we can tell that the chloride ion will not have any basic activity, since HCl is a strong acid and fully dissociates in solution..
Is hno3 an acid?
Nitric acid is a highly acidic substance and a strong oxidizing agent. Its physical state is a colorless or slightly yellowish liquid. The chemical formula of nitric acid is HNO3 and it is made up of one hydrogen atom, one nitrogen atom, and three oxygen atoms.

Why is nitric acid yellow?
Why does concentrated nitric acid turn yellow on exposure to sunlight? … Nitric acid decomposes even at room temperature, especially in the presence of sunlight to liberate reddish brown nitrogen dioxide gas. This gas dissolves in the excess of acid and turns faint to give a yellowish colour to the acid.
Which is weakest acid?
Oxalic acid is the weakest acid.
Is HCl a weak acid?
A strong acid is an acid which is completely ionized in an aqueous solution. Hydrogen chloride (HCl) ionizes completely into hydrogen ions and chloride ions in water. A weak acid is an acid that ionizes only slightly in an aqueous solution. … Because HCl is a strong acid, its conjugate base (Cl−) is extremely weak.
What is pH of 1m h2so4?
The pH of 1M sulfuric acid is 0.
Is hno3 a strong acid or weak acid?
If you see any other acid or base than one of these strong ones it will be a weak acid or base (unless I specifically say otherwise in the problem). The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only).
Is Na2CO3 an acid or base?
Na2CO3 is neither an acid nor a base. It is a salt.
Is KCl an acid or base?
The ions from KCl derive from a strong acid (HCl) and a strong base (KOH). Therefore, neither ion will affect the acidity of the solution, so KCl is a neutral salt.
What are the 7 strong acids?
There are 7 strong acids: chloric acid, hydrobromic acid, hydrochloric acid, hydroiodic acid, nitric acid, perchloric acid, and sulfuric acid. Being part of the list of strong acids doesn’t give any indication of how dangerous or damaging an acid is though.
Is Na2CO3 basic?
Na2CO3 is a salt of Strong base (NaOH) and Weak acid (H2CO3). So, its nature is basic.
Is the pH scale?
The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic.
Is hno3 an acid or a base?
HNO3 is a strong acid, sometimes a base, nitrating agent and a strong oxidising agent. It works as a base in the presence of a stronger acid.
Is h2so4 acid or base?
Absolutely H2SO4 is acid. It’s acidic nature is due to H+ ion present in them. When a molecule of H2SO4 is comes in the contact of water it breaks down into H+ and HSo4- ion. So, 1 H+ ion is present due to which H2SO4 Become acidic.
What is the most powerful acid?
carborane acidThe world’s strongest acid, at least a million times more potent than concentrated sulphuric acid, has been made in a lab in California. Perhaps confusingly, it is also one of the least corrosive. The compound, called a carborane acid, is the first ‘superacid’ that can be stored in a bottle, say its creators.
Is NH4Cl acidic or basic?
A salt formed from reaction of a weak base and a strong acid should give an acidic solution. For example, NH4Cl is formed from the reaction of NH3, a weak base, and HCl, a strong acid. The chloride ion will not hydrolyze.
Is acetic acid a strong acid?
A strong acid is an acid which is completely ionized in an aqueous solution. Hydrogen chloride (HCl) ionizes completely into hydrogen ions and chloride ions in water. A weak acid is an acid that ionizes only slightly in an aqueous solution. Acetic acid (found in vinegar) is a very common weak acid.
