Why is a indicator's reaction in acids and bases a chemical change?
When an indicator is added to an acid or base, it undergoes a chemical reaction with the hydrogen or hydroxide ions present in the solution. This reaction causes a change in the color of the indicator, indicating a shift in the pH of the solution. Since a new substance with different properties is formed during this reaction, it is considered a chemical change.
When an alkali metal reacts with water it produces what?
When an alkali metal reacts with water, it produces an alkali metal hydroxide and hydrogen gas. This is a highly exothermic reaction, with the alkali metal displacing hydrogen from the water molecule.
A sample of hydrogen gas is generated from a...?
Hydrogen can by generated, for example, from the reaction between alkali metals and water.
What metal reacts by hydrogen gas with vigorously?
Alkali metals, such as sodium (Na) and potassium (K), react vigorously with water to produce hydrogen gas. When these metals come into contact with water, they undergo a rapid oxidation reaction, releasing hydrogen gas and forming hydroxides. This reaction can be explosive, especially with heavier alkali metals.
The word equation for the reaction of alkali metals with water?
Alkali Metal + Water ------> Alkali Hydroxide + Hydrogen Alkali Metal Oxide + Water ------> Alkali Hydroxide + Water Example: ================ Sodium + Water ------> Sodium Hydroxide + Hydrogen 2 Na + 2 H2O --------> 2 NaOH + H2
Is adding acid to alkali chemical or physical?
Adding acid to alkali is a chemical process because it results in a chemical reaction that forms water and a salt. This reaction involves the breaking and forming of chemical bonds, resulting in a new substance being produced.
Is Hydrogen oxide acid or alkali?
Hydrogen oxide is neither an acid nor an alkali. It is water, which is a neutral substance.
Is sodium hydroxide and hydrogen gas a chemical property?
No, they are two separate chemical substances. A property is something you can say about a substance. For instance, a property of sodium hydroxide is that it is a strong alkali. A property of hydrogen is that it is much less dense than air. In case you were trying to ask if they undergo a chemical reaction with each other, the answer is no.

What does acid and an alkali together do?
When an acid and an alkali are mixed together, they undergo a neutralization reaction where the hydrogen ions (H+) from the acid react with the hydroxide ions (OH-) from the alkali to form water. This reaction also produces a salt as a byproduct. The result is a solution that is closer to neutral on the pH scale.
When an alkali metal reacts with water it produces what?
When an alkali metal reacts with water, it produces an alkali metal hydroxide and hydrogen gas. This is a highly exothermic reaction, with the alkali metal displacing hydrogen from the water molecule.
What is the name of the chemical reaction between an acid or an alkali?
The reaction between an acid and an alkali is known as a neutralization.
What is alkalis acid?
Alkali isn't an acid. Alkali and acid are terms used when the pH of a substance is a certain number, for example if a substance has a pH of 1, 2, 3, 4, or 5, then the substance is an acid. If the pH is 11, 12, 13, 14 or 15, then the substance is an alkali.
What is the speical name for the chemical reaction between an acid and an alkali?
hi the answer is chemical and its a reaction made by the dark side
What is the name of the reaction when an acid and alkali react together?
Neutralisation, and yes that is how you spell it
What happens when you add an alkali to an alkali?
A chemical reaction. Acid + alkali = salt + water eg H2SO4 + 2NaOH = Na2SO4 + 2H2O Sulfuric acid + Sodium Hydroxide = Sodium Sulfate + water Whan as acid meets an alkali they create a chemical reaction. If there is an acid and you add a weak alkali you should bring it down to neutral.
What is a chemical called which is not an acid or alkali?
A substance that is neither an acid nor an alkali is generally referred to as a neutral substance. Water is a common example of a neutral chemical compound.
