The common name of the compound CaOCl2 is bleaching powder.
CaSO4.1/2H2O + H2O → CaSO4.2H2O Plaster of Paris Gypsum
Carbon dioxide gas will evolve and sodium carbonate will be formed. 2NaHCO3 ➝ Na2CO3 + CO2 + H2O
Washing soda or sodium carbonate decahydrate (Na2CO3.10H2O)
Slaked lime is the substance which reacts with chlorine to give bleaching powder. Ca(OH)2 + Cl2 → CaOCl2 + H2O Slaked lime Bleaching powde...
A soil usually becomes acidic when there is either a high peat content or, iron minerals or there are some rotten vegetables in the soil. In order to ...
Yes, basic solutions also have H+. As the solutions are prepared in water and water being a weak electrolyte, it dissociates into H+ and OH– but the n...
The acidic nature of a solution is directly related to the concentration of H+. As the concentration of H+ increases, the acidic nature of the solutio...
Correct answer: (c) endoplasmic reticulum Explanation: The endoplasmic reticulum helps in the manufacture of proteins and fat molecules or lipids ...
Correct answer: (a) Robert Hook Explanation: The first person to see a cell was Robert Hook. He used a very primitive microscope and observed empt...
Correct answer: (d) tungsten Explanation: The most commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony and tellurium.
Correct answer: (c) humidity Explanation: Humidity cannot be considered as matter as it does not have mass and volume.
Correct answer: (c) Mercury Explanation: At room temperature, mercury (Hg) exists in liquid state. Non metal bromine is also in liquid state at ro...
Correct answer: (a) water Explanation: The strongest intermolecular force of attraction is intermolecular hydrogen bonding. The volatility of wate...
Correct answer: (a) condensation Explanation: Because, in condensation the liquid or the solution is cooled .means it is the process of cooling do...
The pH of a solution is inversely proportional to the concentration of H+ in solution. Lesser the pH of the solution, more will be the H+ concentratio...
Sodium hydroxide (NaOH) is a strong base. It immediately dissociates in solution to give OH– and cations. Upon dissolving more of the base in the solu...
An acid dissociates into hydronium ions (H3O+) and anions when dissolved in water. Upon dilution, the volume of the solution increases and the number ...
Mineral acids such as, H2SO4, HNO3, HCl, etc. have strong affinity for water, so dilution of acid is highly exothermic in nature. This heat may cause ...
A dry HCl gas has no H+ so it does not show any acidic character therefore, no change in colour takes place until we moisten the litmus paper.
