Calcium is not used in the lab preparation of hydrogen because it reacts with water to form calcium hydroxide and hydrogen gas, making it an inefficient method for producing pure hydrogen. Other methods such as using metals like zinc or aluminum are preferred for lab preparation of hydrogen as they do not form unwanted byproducts.

Why nitric acid is not used in lab preparation hydrogen?
Nitric acid is a strong oxidizing agent that can react violently with reducing agents such as hydrogen, leading to potential explosions. This makes it unsafe to use nitric acid in the lab for the preparation of hydrogen gas. Preferred methods for generating hydrogen gas typically involve non-oxidizing acids like hydrochloric acid reacting with a metal like zinc.
How do you produce hydrogen in lab?
Hydrogen can be produced in a lab by reacting a metal such as magnesium or zinc with an acid such as hydrochloric acid. The reaction releases hydrogen gas as a byproduct. Alternatively, electrolysis of water can also be used to produce hydrogen by passing an electric current through water to split it into hydrogen and oxygen gases.
What is the enzyme we studied in hydrogen peroxide yeast lab?
The enzyme studied in the hydrogen peroxide yeast lab is catalase. Catalase helps to break down hydrogen peroxide into water and oxygen.
What does Ca on a lab report mean?
"Ca" on a lab report likely refers to calcium. It is a measurement of the amount of calcium present in a sample, typically reported in units such as mg/dL or mmol/L. This test is often done to assess bone health, nerve and muscle function, and overall calcium metabolism in the body.
Industrial preparation of NaOH with diagram?
The industrial preparation of sodium hydroxide (NaOH) is commonly done through the chloralkali process, where a concentrated solution of sodium chloride (brine) is electrolyzed to produce chlorine gas, hydrogen gas, and sodium hydroxide. The diagram would typically show an electrolysis cell with an anode, a cathode, and a brine solution. The anode oxidizes chloride ions to produce chlorine gas, while the cathode reduces water to hydrogen gas and hydroxide ions, which then combine to form sodium hydroxide.

Why is granulated zinc preferred for lab preparation of hydrogen?
Granulated zinc is preferred for the lab preparation of hydrogen because it has a high surface area, allowing for better reactivity with acids to produce hydrogen gas more efficiently. The granules provide a larger surface for the reaction to occur, leading to faster and more complete production of hydrogen compared to other forms of zinc. Additionally, granulated zinc is easy to handle and measure, making it convenient for laboratory use.
Why is good preparation in lab investigations?
good preparation is good for lab investigations as there are toxic gases in the labs hence someone should know well on the apparatus to use to take precise action

What is the strongest chemical in a science lab?
The strongest chemical in a science lab is Hydrogen Fluoride. The second strongest chemical is Hydrogen Chloride. Hydrogen Fluoride isn't the world's strongest chemical. The King of Liquids is the mixture of 1 Hydrogen Fluoride and 3 Hydrogen Chloride.
