Hydrogen gas according to the following formula: Zn + 2HCl --> H2 + ZnCl2
Hydrogen Gas
It increases.
Neutralization
salt and water
Carbon don't react with acids, except concentrated Nitric acid. Concentrated nitric acid reacts with carbon to produce Water, Carbon dioxide, and Nitrogen dioxide.
Sodium Chloride , water and Carbon Dioxide is formed causing "gassing"
Carbon Dioxide
Potassium reacts explosively.
It increases.
When sodium bicarbonate reacts with dilute hydrochloric acid they produce carbon dioxide (CO2)
Neutralization
CO2
Calcite
Hydrogen gas
Concentrated hydrochloric acid is more reactive than dilute hydrochloric acid. When concentrated hydrochloric acid reacts with magnesium, it produces magnesium chloride and hydrogen gas more quickly and vigorously compared to when dilute hydrochloric acid reacts with magnesium. This is due to the higher concentration of hydrogen ions in concentrated hydrochloric acid, leading to a faster and more intense reaction.
Hydrogen.
NiCO3 + HCl =NiCl2 + H2O +CO2
Hydrochloric acid can be either concentrated or dilute, depending on its specific concentration in water.
