What happens when lead is added to nitric acid?
Production. Lead nitrate is produced by reaction of lead(II) oxide with concentrated nitric acid: PbO + 2 HNO3(concentrated) → Pb(NO3)2↓ + H2O. It may also be obtained evaporation of the solution obtained by reacting metallic lead with dilute nitric acid.
Which reaction can be predicted from the activity series?
The periodic table or an activity series can help predict whether single-replacement reactions occur. A double-replacement reaction exchanges the cations (or the anions) of two ionic compounds. A precipitation reaction is a double-replacement reaction in which one product is a solid precipitate.
What happens when nickel Ni is added to a solution of potassium chloride KCL?
Predict what happens when nickel is added to a solution of potassium chloride. No reaction occurs. Calcium chloride forms.
Which observation does not indicate that a chemical reaction has occurred?
Chemsitry Chapter 8
| Question | Answer |
|---|---|
| A chemical reaction has NOT occurred if the products have __________? | the same chemical properties as the reactants |
| Which observation does NOT indicate that a chemical reaction has occurred? | change in total mass of substances |
Why lead reacts with nitric acid but gold does not?
Explain why lead reacts with nitric acid but gold does not. Lead is above hydrogen in the reactivity series, while gold is below hydrogen. This means that lead is more reactive and loses electrons more readily to form lead(II) ions.
What can you predict by using an activity series quizlet?
Activity series are used to help predict whether certain chemical reactions will occur. The information that they contain is used as a general guide for assessing relative reactivity of a substance and for predicting reaction outcomes.
How do you think an activity series could help you to predict whether or not a reaction could occur?
Once organized, an activity series helps us to predict if a reaction will occur when a piece of elemental metal is placed in water, an acid solution, or a solution containing the ion of another metal. In a solution or compound, an elemental metal will displace any metal lower than it on the activity series.
When a solution of nitric acid and sodium hydroxide are mixed What precipitate if any is formed?
Explanation: Nitric acid and sodium hydroxide will neutralize each other in a 1:1 mole ratio, i.e. every mole of nitric acid will consume 1 mole of sodium hydroxide, to produce water and aqueous sodium nitrate, NaNO3 .
Which observation indicates that a chemical reaction has occurred?
Some signs of a chemical change are a change in color and the formation of bubbles. The five conditions of chemical change: color change, formation of a precipitate, formation of a gas, odor change, temperature change.
What observations might indicate that a chemical change has occurred quizlet?
What observations might indicate that a chemical change has occurred? Three common types of evidence for a chemical change are a change in color, the production of a gas, and the formation of a precipitate.
What happens when lead is reacted with nitric acid?
Lead when reacted with nitric acid forms lead (II) nitrate, nitrogen oxide and water. Since the solvent is concentrated nitric acid (in which lead (II) nitrate has very low solubility) and the resulting solution contains nitrate ions, anhydrous crystals of lead (II) nitrate spontaneously form as a result of the common ion effect.
How can nitrate be obtained from nitric acid?
Lead(II) nitrate can be obtained by dissolving metallic lead in aqueous nitric acid: $$\\ce{Pb + 4 HNO3 → Pb(NO3)2 + 2 NO2 + 2 H2O}$$
Which is the oxidizing agent of nitric acid?
The products will be Pb(NO₃)₂, NO₂ and H₂O. Nitric acid is a very powerful oxidizing agent. It oxidized H₂ to H₂O.

Which is more feasible a nitrate or copper reaction?
The nitrate ion equilibrium has the more positive E° value and will move to the right. The copper E° value is less positive. That equilibrium will move to the left. The movements that the E° values suggest are possible, and so a reaction is feasible.
