Why does zinc react faster with hydrochloric acid?

Powdered zinc has greater surface area exposed to hydrochloric acid. Generally, as particle size decreases, surface area increases, and reaction rate also increases.

Why dilute hydrochloric acid reacts faster with powdered zinc than with granulated zinc?

(1) In a reaction, the rate of the reaction depends upon the particle size of the solid reactant as the reaction takes place on the surface only. Smaller the particles are, the more will be their total surface area and faster will be the rate of the reaction. (2) Hence, zinc powder reacts much faster with dil.

When zinc reacts with very dilute nitric acid it produces?

When zinc reacts with very dilute nitric acid it produces NH4.NO3.

When dilute hydrochloric acid reacts with zinc metal Which of the following is needed for the identification of exerted gas?

The reaction between zinc metal and HCl Zinc reacts easily with the acid to produce hydrogen bubbles. It is a single displacement reaction in which hydrogen is displaced by zinc metal to form hydrogen gas and a salt, zinc chloride. To produce bubbles of hydrogen, zinc reacts rapidly with the acid.

When dilute hydrochloric acid reacts with zinc metal Which of the following is needed for the identification of excreted gas?

Answer: The pH paper will be required to identify the gas evolved when dilute hydrochloric acid reacts with zinc metal. Hence the correct answer is option D. The pH indicator can be termed as a halochromic chemical that is added in very less amounts to any solution so that the pH of solution is visually determined.

Why zinc does not react with nitric acid?

Zinc. Chromium do not dissolve in concentrated nitric acid because of the formation of a passive film of oxide on the surface.

How does zinc react with nitric acid?

Zinc reacts with concentrated Nitric acid to produce Zinc nitrate, nitrogen dioxide and water.

How does zinc react with dilute acid?

Zinc is more reactive than hydrogen and it displaces hydrogen from dilute acids. Zinc reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas is evolved.

What would happen when zinc reacts with dilute hydrochloric acid represent the reaction in word equation and chemical equation?

The reaction between zinc and HCl is given by the symbolic equation Zn + HCl → ZnCl2 + H2. Note that H2 is hydrogen gas.
