Acids Bases and Salts Chapter Wise Important Questions Class 10 Science
This precipitate is removed by filtration. Write equations for the following reactions i Dilute sulphuric acid reacts with zinc granules ii Dilute hydrochloric acid reacts with magnesium ribbon. Is this solution acidic, basic or neutral?
What will you observe when: i Red litmus is introduced into a solution of sodium sulphate. Blue litmus is introduced into a solution of ferric chloride Ans.
Since the acid is strong, the solution will be acidic. Therefore the colour of blue litmus will change to red. A first aid manual suggests that vinegar should be used to treat wasp sting and baking soda for bee stings. If baking soda is not available in the house, solution of ammonium hydroxide NH 4 OH can be used for the same purpose. Does Tartaric acid helps in making cake or bread fluffy.
No, tartaric acid does not evolve any carbon dioxide during baking. Explain why? When exposed to atmosphere, it becomes moist. Therefore common salt becomes sticky during the rainy season. A compound X of sodium is commonly used in kitchen for making crispy pakoras. It is also used for curing acidity in the stomach.
What is its chemical formula? State the reaction that takes places when it is heated during cooking? Compound X is a constitute of baking powder. It is also called as baking soda. Chemically, the compound is sodium hydrogen carbonate with formula NaHCO 3. Since the volume increases, the acid starts flowing out of the bottle. How is plaster of Paris chemically different from gypsum?
How may these be inter converted? Write one use of plaster of Paris? Plaster of Paris is different from Gypsum as it is prepared from heating gypsum. Plaster of Pairs is a major constituent of surgical bandages used for setting fractured bones. Before applying on fractured bone, it is made wet with water and as a result of hydration it changes into gypsum which keeps the bones in position.
These may be interconverted by the reaction. Red litmus acquires a blue colour. State the chemical property in each case on which the following uses of baking soda are based i As an antacid ii As a constituent of baking powder. Give the chemical for baking soda Ans. As a result, the cake becomes porous as well as fluffy. The chemical formula of baking soda is. The gas evolved extinguishes a burning candle. Write a balanced chemical equation for the reaction, if one of the compounds formed is calcium chloride.
While compounds like alcohol and glucose do not release hydrogen ions. Therefore they do not show acidic properties. Which solution has more hydrogen ions concentration? Which is acidic and which one is basic? A solution having pH less than 7 is acidic and that having pH more than 7 is basic. Under what soil condition do you think a farmer would treat the soil of his field with quicklime calcium oxide or slaked lime calcium hydroxide or chalk calcium carbonate.
The farmer would treat the soil of his field with quicklime calcium oxide or slaked lime calcium hydroxide or chalk calcium carbonate when field has become acidic to neutralize the effect of acid. A milkman adds a very small amount of baking soda to fresh milk. This is because sodium hydrogen carbonate baking soda is basic in nature.
This prevents the milk from souring. This prolongs the time taken by milk to set as curd. What is a neutralization reaction? Give two examples. The reaction between an acid and a base to give salt and water is called neutralization reaction. Give two important uses of washing soda and baking soda. Compound P forms enamel of teeth. It is the hardest substance of the body. It does not dissolve in water but it is corroded when pH in the mouth is below 5.
How does tooth paste prevent dental decay? Using toothpastes, which Are generally basic, for cleaning the teeth can neutralize the excess acid and prevent Tooth decay. The oxide of a metal M was water soluble when a blue litmus strip was dipped in This solution, it did not go any change in colour. Predict the nature of oxide. The Metal oxide MO is of basic in nature. A road tanker carrying an acid was involved in an accident and its contents spilled on the road, iron drain covers began melting and fizzing as the acid ran over them.
A Specialist was called to se if the acid actually leaked into the nearby river. Suggest a better name that should have been used. If the colour Changes to red this means that some acid has gone in to the river. A student heated a few crystals of copper sulphate n a dry boiling tube. Value 4.
