What happens when lead reacts with dilute sulphuric acid?

What happens when lead reacts with dilute sulphuric acid?

When lead oxide react with dilute sulphuric acid, a thin layer of lead sulphate is formed on the surface of the solid lead oxide.

What happens when lead reacts with dilute acid?

Lead has no noticeable reaction with either of the dilute acids because lead(II) chloride and lead(II) sulfate are insoluble in water. Any reaction which occurs will coat the lead with insoluble lead(II) chloride or lead(II) sulfate and stop any further acid getting at it.

Does PB react with conc H2SO4?

Red lead (Pb3O4) reacts with conc. HCl and conc. H2SO4 separately liberating and gases respectively.

Is lead oxide soluble in dilute sulphuric acid?

Lead oxide is poorly soluble in water. The solubility of lead oxide in dilute sulfuric acid is also very low. When lead oxide is added to dilute sulfuric acid, a thin layer of lead sulfate is formed on the surface of the solid lead oxide.

Which of the following does not react with dilute hydrochloric acid and dilute sulphuric acid both?

The correct answer is Copper. Copper does not react with dilute hydrochloric acid even on heating but reacts with sulphuric acid.

Why lead does not react with dilute HCl or dilute H2 S o4?

Though lead is above hydrogen in the activity series, it does not react with dilute hydrochloric acid or dilute sulphuric acid.

Which reaction will not occur using cold dilute sulphuric acid?

With cold concentrated sulfuric acid, such metals as iron and aluminum do not react, as they are covered with an oxide film. This process is called passivation.

What is Dil h2so4?

Dilute sulfuric acid is a strong acid and a good electrolyte; it is highly ionized, much of the heat released in dilution coming from hydration of the hydrogen ions. The dilute acid has most of the properties of common strong acids.

What solution does Pb react with?

Lead reacts slowly with hydrochloric acid and nitric acid, HNO3. In the latter case, nitrogen oxides are formed together with lead(II) nitrate, Pb(NO3)2.

Does lead II oxide react with sulfuric acid?

Both the lead and lead oxide are in a solution of sulfuric acid (H2SO4) and water (H2O). At the positive electrode, the chemical reaction is PbO2 + SO−/4 − + 4H+ + 2e− → PbSO4 + 2H2O + (1.68 V).

What is the formula for lead II oxide?

PbO
Lead(II) oxide/Formula

What happens when lead reacts with sulphuric acid?

Lead reacts slowly with dilute sulfuric acid to make lead (II) sulfate and hydrogen gas. The driving force has to be the loss of hydrogen (leChatelier) as both lead and lead sulfate are solids and not in solution.

Why should the value of ΔG° be negative for lead sulfate?

To move in the forward direction the value of ΔG° should be negative. Lead is a solid, and in a solution of sulfuric acid, the acid surrounds the metal and reacts over the whole surface. Lead sulfate is produced which is insoluble and forms a tight coating over the surface of the lead.

What happens when copper reacts with dilute sulphuric acid?

Dilute sulphuric acid simply acts as an acid. H2SO4+Mg→MgSO4+H2. So, one might expect to get something similar to this, with copper metal. But, copper is less reactive than even hydrogen, and is unable to displace the hydrogen in the sulphuric acid. So, Cu+dil. H2SO4 remains as it is – no reaction.

Is sulphuric acid a good oxidising agent?

SULPHURIC ACID (conc) is a good oxidising agent. It oxidises Pb (2+) to Pb (4+) and itself gets reduced to SO2. What is the reaction of lead with dilute sulphuric acid?
