Is k2co3 an acid or base?
Potassium carbonate (K2CO3) is a commonly used base in organic chemistry.
The pKa of its conjugate acid is 10.25.
It is commonly used to deprotonate moderately acidic protons such as phenols (pKa ~10) and 1,3-dicarbonyl compounds (pKa ~9-13)..
What is k2co3 used for?
Potassium carbonate, K2CO3, appears as a white powder or as colorless solid crystal and has a salty taste. Also known as potash or pearl ash, it may be used in pharmaceutical laboratories as a drying agent or as a source of potassium. It also used in fire extinguishers, to make soap, to make glass, and to soften water.
Is lino3 a base or acid?
LiNO3 is a salt resulting out of a strong acid such as HNO3 (Nitric acid ) and a strong base such as LiOH (Lithium hydroxide) and hence is a strong acid-strong base salt.
Is nh4f an acid or base?
KaHF=6.6*10^-4. I found for NH4F to be acidic by finding Ka (NH3) being greater than Kb (HF). It says it’s acidic salt, not neutral salt.
What is the pH of acetic acid?
Acetic acid is a weak monoprotic acid. In aqueous solution, it has a pKa value of 4.76. Its conjugate base is acetate (CH3COO−). A 1.0 M solution (about the concentration of domestic vinegar) has a pH of 2.4, indicating that merely 0.4% of the acetic acid molecules are dissociated.
Will NH4Cl form a basic solution?
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. … A salt formed from reaction of a strong base and a weak acid should give a basic solution.
Is k2co3 basic?
Potassium carbonate (K2CO3) is a white salt, soluble in water (insoluble in ethanol) which forms a strongly alkaline solution. It can be made as the product of potassium hydroxide’s absorbent reaction with carbon dioxide.

Will k2co3 form a basic solution?
Therefore, it will attract H atoms from water to form OH-ions and make a basic solution. For K2CO3, what you didn’t get was that CO3 is the conjugate baseof a weak acid (HCO3). Therefore, CO3 will produce a basic solutionas well. This is why these three work.
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 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.
