Why does not silver evolve hydrogen on reacting with dilute sulphuric acid?
it is because, silver lies below hydrogen in electrochemical series. so it cannot reduce the hydrogen and replace it.
Is hydrogen chloride and acid or alkaline?
hydrogen chloride is an acid
How can an acid produce hydrogen gas?
When an acid reacts with a material, the hydrogen in the acid is released.
Why metals release hydrogen gas?
Metals will release hydrogen gas when reacting with an acid (or in some cases, water). This is because acids contain hydrogen, and many metals are higher on the reactivity series than hydrogen, meaning they will replace it in a compound. For example, zinc reacts with hydrochloric acid Zn + 2HCl --> ZnCl2 + H2 The zinc replaces hydrogen in the hydrochloric acid, forming zinc chloride and releasing elemental hydrogen in the process.
Is Hydrogen Fluoride a strong acid?
Hydrogen fluoride is a weak acid.
Will cu replace H from H2SO4?
No. Copper will not replace hydrogen in sulfuric acid because it is less reactive than hydrogen.
Non-metal do not replace hydrogen from acid why?
because metal contain positive ions and hydrogen too
When -NH2 and -COOH replace hydrogen atome it makes a?
An Amino Acid is formed.
Can magnesium replace after adding into acid?
yes if put into HCl it will replace the H and produce hydrogen gas and magnesium chloride
Does sodium replace hydrogen in a single replacement reaction?
Yes, when sodium reacts with Hydrochloric acid it replaces the hydrogen as hydrogen gas. 2Na + 2HCl = 2NaCl + H2
Why does not silver evolve hydrogen on reacting with dilute sulphuric acid?
it is because, silver lies below hydrogen in electrochemical series. so it cannot reduce the hydrogen and replace it.
When both -NH2 and -COOH replace hydrogen atoms on the same carbon atom and what is formed?
When both -NH2 and -COOH replace hydrogen atoms on the same carbon atom, an amino acid is formed.
Why slver does not evolve hydrogen while reacting with dil sulphuric acid?
it is because, silver lies below hydrogen in electrochemical series. so it cannot reduce the hydrogen and replace it.
What happen when hydrochloric acid is added to the zinc powder?
Zinc will replace hydrogen from its compound (H Cl) to form Zn Cl and hydrogen is liberated.
When both nh2 and COOH replace hydrogen atoms on the same carbon what is formed?
it forms an amino acid
Why do metals replace hydrogen from acid but non metals do not?
This is because metals have positive ions and so does hydrogen. Hence the nature of their reactivity is same but the value of reactivity is different. Therefore metals replace hydrogen in a reaction while non metals dont...
