Neutralization reaction The reaction of an acid and a base to form water is called a neutralization reaction. When an acid and a base react, hydrogen ions from the acid (H+) and hydroxide ions from the base (OH-) react in … more
Law of Definite Proportions In a reaction where hydrogen gas is burned to produce water, two hydrogen atoms combine with one oxygen atom. Hydrogen gas and oxygen gas always react in a ratio of 2:1 to produce water. In this … more
2●\(\rightleftharpoons\)● Chemical equilibrium In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations that have no further tendency to change with time. In an equilibrium state at a constant temperature, the … more
A precipitation reaction is a type of reaction when two solutions react to form an insoluble solid (ionic salt) A lot of ionic compounds dissolve in water and exist as individual ions. But when two ions find each other forming … more
Paraffin, the main ingredient of candles Paraffin, the main ingredient of candles, is alkane hydrocarbons in which 20 to 40 carbon atoms are linked in a chain. It does not dissolve in water as a polar solvent but dissolves well … more
Ammonia synthesis process Ammonia is a widely used material, such as fertilizers, plastic materials, medicines, and daily necessities. Currently, ammonia is being mass-produced at factories. However, when we did not know how to synthesize ammonia in the past, we thought … more
Chemical Reactions in Gas Phase Hydrogen gas and oxygen gas react to produce water vapor. The hydrogen gas and the oxygen gas react at a volume ratio of 2: 1 to generate 2 volumes of water vapor. When the gas … more
Pressure and chemical equilibrium transfer According to Le Châtelier, if the pressure is increased, the equilibrium position will move to reduce the pressure. The system can reduce the pressure by reacting in such a way as to produce fewer molecules. … more
What will the reactant and product concentration curve look like over time? Click the button to start the synthesis reaction. Reaction rate Reaction rate refers to the degree to which a chemical reaction occurs quickly or slowly. The rate of … more
Lead iodide sediment formation reaction If you continue to add the lead nitrate solution to a certain amount of potassium iodide solution, the amount of sediment produced will continue to increase at the beginning and will no longer increase at … more
Magic to turn hard water into soft water Soap does not dissolve well in hard water. On the other hand, soap is well solved in soft water. This is because hard water contains calcium ions(Ca2+) or magnesium ions(Mg2+). Ions dissolved … more
