What volume of 1.050 M potassium hydroxide is required to react with 22.2 ml of 0.755 M nitrous acid?
First, calculate the number of moles of nitrous acid using the concentration and volume. Then, based on the balanced chemical equation for the reaction between potassium hydroxide (KOH) and nitrous acid (HNO2), determine the mole ratio between them. Use this ratio to find the volume of potassium hydroxide required to react with the calculated moles of nitrous acid.
How does magnesium react in acid?
Magnesium reacts with acid to produce magnesium ions and hydrogen gas. The magnesium metal dissolves in the acid while releasing hydrogen gas as a byproduct. This reaction is typically fast and exothermic.
What potassium is used to patina copper?
Potassium sulfide or potassium polysulfide is commonly used to patina copper. These chemicals react with the copper to create a dark patina on the surface. Always use these chemicals with caution and proper safety equipment, as they can be hazardous.
What is observed when potassium bromide and sulphuric acid react?
When potassium bromide and sulfuric acid react, potassium sulfate and hydrogen bromide gas are produced. This reaction is characterized by the liberation of hydrogen bromide gas, which can be identified by its pungent odor and may form a white mist when exposed to moist air due to its reaction with water vapor.
What is mechanism of H2SO4 plus K2CO3?
When sulfuric acid (H2SO4) reacts with potassium carbonate (K2CO3), a double displacement reaction occurs. The hydrogen ions in sulfuric acid (H2SO4) react with the carbonate ions in potassium carbonate (K2CO3) to form water (H2O) and carbonic acid (H2CO3), which further decomposes into water and carbon dioxide (CO2). The resulting products are water, carbon dioxide, and potassium sulfate (K2SO4).
What 2 metals can explode when mixed with acid?
Sodium and potassium are two metals that can explode when mixed with acids such as hydrochloric acid or sulfuric acid. They react vigorously, producing hydrogen gas which can ignite and cause an explosion.
Does helium react vigorously with acid?
No. helium has completely filled orbitals and does not react with anything else.
Why is it unsafe to add an acid to potassium?
Potassium will react violently, with acid. The reaction can potentially splatter droplets of acid or pieces of burning potassium.
Why does Magnesium React with hydrochloric acid more vigorously than acetic acid?
Magnesium reacts more vigorously with hydrochloric acid because HCl is a stronger acid than acetic acid, so it can more easily donate protons to react with the magnesium. This reaction generates hydrogen gas and forms magnesium chloride. Acetic acid is a weaker acid, so it reacts more slowly and less vigorously with magnesium.
What is the product when hydrochloric acid and potassium hydroxide react together in water?
When hydrochloric acid and potassium hydroxide react together in water, they form potassium chloride (KCl) and water (H2O) as products.
Does potassium oxide react with a carboxylic acid?
Yes, they react tor form water and the corresponding potassium carboxylate salt.
Does potassium carbonate react with hydrochloric acid?
Yes, potassium carbonate (K2CO3) will react with hydrochloric acid (HCl) to form potassium chloride (KCl), carbon dioxide (CO2), and water (H2O) in a double displacement reaction.
Why does concentrated hydrochloric acid not react with potassium a predicted?
Concentrated hydrochloric acid does not react with potassium because potassium is a more reactive metal than hydrogen. When hydrochloric acid reacts with metals, it typically displaces hydrogen gas. However, potassium is so reactive that it can displace hydrogen from hydrochloric acid, creating a violent reaction that can be unsafe.
What does tartaric acid and potassium carbonate make?
Tartaric acid and potassium carbonate react to form potassium bitartrate (cream of tartar), water, and carbon dioxide gas.
How does potassium react with hydrochloric acid?
Hydrochloric acid evaporates off of potassium sulfate when it's produced. This results because potassium chloride is combined with sulfuric acid to create potassium sulfate.
Acid and base that makes potassium iodide?
To make potassium iodide, you would need to first react iodine with potassium hydroxide. This will create potassium iodate, which can then be reduced to potassium iodide using a reducing agent like sulfur dioxide or hydriodic acid.
Does calcium react in acid?
Yes, calcium does react with acids such as hydrochloric acid to produce calcium chloride and hydrogen gas. This reaction is a common example of a metal reacting with an acid to form a salt and hydrogen gas as a byproduct.
