you mean a base or an acid?
K2CrO4 is a base
Potassium perchlorate is a salt. I would expect it to be fairly neutral, given that potassium hydroxide is a very strong base and perchloric acid is a very strong acid.
Potassium Chromate is a base
Potassium chromate is a salt.
Acid = Hydroiodic acid Base = Potassium hydroxide (or any Potassium salt of weak acid)
KCrO4 does not exist it is K2CrO4 and is called Potassium Chromate. Potassium dichromate is K2Cr2O7
Chromic Acid
Chromate
Potassium chromate is a salt.
No, Potassium chromate is a compound
Yes, because it is an ionic compound and may be prepared by neutralizing Potassium hydroxide with Chromic acid.
Reaction of Potassium hydroxide or any potassium salt of a weak acid with chromic acid produces Potassium chromate. KOH + H2CrO4 ----> K2CrO4 + H2O K+ + H2CrO4 ----> K2CrO4 + H+
This is a mixture of 2K+ and Cr2O72- ions in strong sulfuric acid.2CrO4- + 2H+ ----> Cr2O72- + H2Ochromate-yellow -> dichromate-orangeNote:Potassium ions do NOT react, they are tribune-ions
Acid = Hydroiodic acid Base = Potassium hydroxide (or any Potassium salt of weak acid)
KCrO4 does not exist it is K2CrO4 and is called Potassium Chromate. Potassium dichromate is K2Cr2O7
Chromic Acid
K2CrO4 + BaSo4 ----------> BaCrO4 (Precipitate) + K2SO4 Potassium Barium Barium Potassium Chromate Sulphate Chromate Sulphate It Is A Double Displacement Reaction
Chromate
by the reaction of lead nitrate with potassium chromate or potassium dichromate
Potassium hydroxide and acetic acid.
