∙ 12y ago
When potassium chromate (K2CrO4) is added to hydrochloric acid (HCl), a yellow precipitate of chromium(III) hydroxide, Cr(OH)3, forms due to the replacement of the chloride ions by the chromate ions. This reaction can be represented by the equation: 2CrO4^2- + 6H+ -> Cr2O3 + 3H2O.

Which element undergoes Oxidation in k2cro4 na2so3 hcl-kcl na2so4 crcl3 h2o?
Chromium undergoes oxidation in the given chemical equation. In this reaction, chromium changes from a +6 oxidation state to a +3 oxidation state, indicating that it has lost electrons and undergone oxidation.
How do you find the concentration of 3.50g of potassium chromate in 100 ml water?
K2CrO4 Molarity (concentration) = moles of solute/Liters of solution (100 ml = 0.100 Liters ) Find moles K2CrO4 first. 3.50 grams = (1 mole K2CrO4/194.2 grams) = 0.01802 moles K2CrO4 ----------------------------------------------next Molarity = 0.01802 moles K2CrO4/0.100 Liters = 0.180 M K2CrO4 -------------------------
What is the net ironic equation of BaCl2 plus K2CrO4?
BaCl2+K2CrO4--------->BaCrO4+2KCl BaCrO4 is a yellow precipitate.
What is produced by adding HCl and Sodium hydroxide?
When hydrochloric acid (HCl) is added to sodium hydroxide (NaOH), a neutralization reaction occurs that produces water (H2O) and sodium chloride (NaCl), which is also known as table salt. The balanced chemical equation for this reaction is: HCl + NaOH -> H2O + NaCl.
Is K2CrO4 organic?
inorganic
Is adding HCl to Mg and physical or chemical change?
Adding HCl to Mg will result in a chemical change. The HCl will react with the Mg to form magnesium chloride and hydrogen gas. This demonstrates a chemical reaction where new substances are formed.
How do you make 1N HCL from 1N HCL?
Take specific volume of 3N solution and increase the volume three times by adding distilled water.
What is the name of this formula k2CrO4?
The name of the formula K2CrO4 is potassium chromate.
Is adding NaOH to HCL chemical or physical change?
When adding NaOH to HCl, a chemical change occurs because the two substances react to form a new compound, NaCl (table salt), and water. This is evidenced by the formation of a new substance with different properties than the original reactants.
What is the effect of HCl on the pH if water?
Adding hydrogen chloride to water the pH decrease.
What are the functions of NaOH in benzoylation of amine?
in benzoylation of amine, HCl is produced which by adding NaOH, HCl consumed and the raction proceed for production of further benzoylation product.
