Water is mainly water molecules and it reduces the concentration of ions in the solution by adding water to an acid or base. (a) Hydrogen is found in minute traces in the Earth’s crust and the Earth’s atmosphere. i. All metals react with acids to give hydrogen. Although there are many acids, there are several properties they have in common. Iron reacts with the steam and the reaction is reversible. Dilute acids contain a large amount of water. Concentration of the acid – if the acid is too dilute the reaction is very slow. (e) No, there is no reaction between substance B and dilute hydrochloric acid because copper does not displace hydrogen from acids. The mixture of carbon dioxide and hydrogen is forced through cold water under pressure at 30 atmospheric pressure or through caustic potash solution which dissolve carbon dioxide leaving behind hydrogen gas. Iron ii. All acids may be organic or inorganic, releasing hydrogen ions (H+) in water. Example: H= 1 (He=2) F= 2,7 (Ne=2,8) Cl= 2,8,7 (Ar=2,8,8), H 1e– → H1+ Li 1e– → Li1+ Na 1e– → Na1+, H + 1e– → H1- F + 1e– → F1- Cl + 1e– → Cl1-, forms NaH (electrovalent)forms CH4(covalent), forms NaCl (electrovalent) forms CCl4 (covalent), Diatomic molecules are formed. This is why we do not store liquid food in metallic containers. Observation and conditions Hydrogen gas when passed through molten sulphur, it reacts to give another gas, hydrogen sulphide.
