Is HCl base or acid?
strong acidHCl is a strong acid because it dissociates almost completely. By contrast, a weak acid like acetic acid (CH3COOH) does not dissociate well in water – many H+ ions remain bound-up within the molecule. In summary: the stronger the acid the more free H+ ions are released into solution.

Is HNO3 a base or acid?
HNO3 is a potent acid, a base, a nitrating agent and a heavy oxidising agent at times. In the presence of a stronger acid, it serves as a base. As the conjugate base is more stable, nitric acid is a stronger acid than nitrous acid.
Is kno2 a base or acid?
basicTherefore, neither ion will affect the acidity of the solution, so KCl is a neutral salt. Although the K + ion derives from a strong base (KOH), the NO 2 − ion derives from a weak acid (HNO 2). Therefore the solution will be basic, and KNO 2 is a basic salt.

Is HNO3 an acid?
Nitric acid (HNO₃) is a colorless liquid with yellow or red fumes with an acrid odor. Exposure to nitric acid can cause irritation to the eyes, skin, and mucous membrane; it can also cause delayed pulmonary edema, pneumonitis, bronchitis, and dental erosion. Nitric acid is highly corrosive.
What is the chemical formula for potassium chlorate?
Chemical compound. Potassium chlorate is a compound containing potassium, chlorine and oxygen, with the molecular formula KClO 3. In its pure form, it is a white crystalline substance. It is the most common chlorate in industrial use.
What is molten potassium chlorate?
Molten potassium chlorate is an extremely powerful oxidizer and spontaneously reacts with many common materials such as sugar. Explosions have resulted from liquid chlorates spattering into the latex or PVC tubes of oxygen generators, as well as from contact between chlorates and hydrocarbon sealing greases.

Which anions have trigonal pyramidal structures?
As predicted by valence shell electron pair repulsion theory, chlorate anions have trigonal pyramidal structures .
Is chlorate a Lewis structure?
Structure and bonding. The chlorate ion cannot be satisfactorily represented by just one Lewis structure, since all the Cl–O bonds are the same length (1.49 Å in potassium chlorate ), and the chlorine atom is hypervalent. Instead, it is often thought of as a hybrid of multiple resonance structures :
