Why no gas is released if sulphur is added to dilute hydrochloric acid?
When sulfur is added to dilute hydrochloric acid, it reacts with the acid to form hydrogen sulfide gas. This gas is colorless and has a strong odor of rotten eggs. The reaction occurs slowly because of the low reactivity of sulfur with hydrochloric acid, resulting in a delayed release of gas.
What does dilute hydrochloric acid do to limestone?
Dilute hydrochloric acid reacts with limestone to form calcium chloride, carbon dioxide, and water. This reaction causes the limestone to break down and dissolve, resulting in the release of gas bubbles and the formation of a calcium chloride solution.
How can you effectively dilute hydrochloric acid for safe handling and use in laboratory experiments?
To effectively dilute hydrochloric acid for safe handling and use in laboratory experiments, you should slowly add the acid to water while stirring constantly. This helps to prevent splashing and potential hazards. Remember to always add acid to water, not the other way around, to avoid dangerous reactions. Additionally, make sure to wear appropriate personal protective equipment, such as gloves and goggles, when working with hydrochloric acid.
How do you mix hydrochloric acid with detergent?
To mix hydrochloric acid with detergent, first dilute the hydrochloric acid with water in a well-ventilated area while wearing appropriate protective gear. Then, slowly add the diluted acid to the detergent while stirring gently to ensure thorough mixing. Be cautious as mixing these chemicals can release toxic fumes and heat.
What would happen if a gold ring were placed in dilute acid?
The gold ring would undergo a chemical reaction in dilute acid, specifically in hydrochloric acid, which can dissolve gold to form a soluble complex. This reaction would slowly erode the gold ring and cause it to dissolve over time.

Why concentrated hydrochloric acid is not used to prepare hydrogen gas in laboratory?
Concentrated hydrochloric acid (HCl) is not typically used to prepare hydrogen gas in the laboratory because it can react violently with some metals, leading to the release of hazardous hydrogen gas and potentially causing explosions. Dilute hydrochloric acid is safer to use for this purpose as it produces hydrogen gas more slowly and can be better controlled.
How can I safely dispose of hydrochloric acid at home?
To safely dispose of hydrochloric acid at home, dilute it with a large amount of water in a well-ventilated area, wear protective gear such as gloves and goggles, and slowly pour the mixture down the drain while running water. Do not mix it with other chemicals and follow local regulations for hazardous waste disposal.
How do you make 50 percent HCL?
To make 50% hydrochloric acid (HCl), you would need to dilute concentrated hydrochloric acid (typically around 37%) with water. Measure out the appropriate amount of concentrated HCl and add an equal volume of water to achieve the desired concentration. Always add acid to water slowly and with stirring to prevent splashing or overheating.
How do you prepare 0.4 M hydrochloric acid?
To prepare 0.4 M hydrochloric acid solution, you can dilute concentrated hydrochloric acid (typically around 12 M) with distilled water in a volumetric flask. Calculate the volume of concentrated acid needed using the formula C1V1 = C2V2, where C1 is the concentration of your concentrated acid, V1 is the volume of concentrated acid needed, C2 is the desired final concentration (0.4 M), and V2 is the final volume of the solution. Always add acid to water slowly and with stirring to avoid splattering and potential hazards.
How do you make 0.6M HCL?
To make 0.6M HCl (hydrochloric acid), you would need to dilute a more concentrated solution of hydrochloric acid with water to achieve the desired molarity. For example, to make 1 liter of 0.6M HCl from concentrated 12M HCl, you would need to mix approximately 50 mL of 12M HCl with 950 mL of water. It is essential to add the acid to water slowly while stirring to prevent splashing and ensure safety.
What are the ways that you can measure the pH of a mixture of potassium hydroxide ans dilute hydrolic acid?
You can measure the pH of a mixture of potassium hydroxide and dilute hydrochloric acid using a pH meter or pH indicator strips. Alternatively, you can perform a titration experiment by slowly adding one solution to the other and monitoring the pH until it reaches a known endpoint.
How can you effectively dilute HCl for safe handling and use in laboratory experiments?
To effectively dilute hydrochloric acid (HCl) for safe handling and use in laboratory experiments, you should slowly add the acid to water while stirring constantly. This helps to prevent splashing and potential hazards. Remember to always add acid to water, not the other way around, to avoid a violent reaction. Additionally, wear appropriate personal protective equipment, such as gloves and goggles, when working with HCl.
