Acids and bases Flashcards
What is the chemical formula of a reverse equation
Give some examples of acids and their chemical formula
Give some examples of alkalis and their chemical formula
What can water molecules break down into?
Hydrogen and Hydroxide ions
Why can alkaline and acidic solutions conduct electricity?
Because they have ions which are free to carry charge.
What does it mean when an acid or alkali has a higher concentration?
That they can conduct better.
When does an alkaline solution form?
When a metal oxide is dissolved in water
When does an acidic solution form?
When a non-metal oxide is dissolved in water.
What does carbon dioxide produce when dissolved in water?
What is a reversible reaction?
It’s when a small portion of water molecules break up to form hydrogen ions and hydroxide ions.some of these hydrogen and hydroxide ions react together to form water molecules.
What is it called when hydrogen and hydroxide ions form together?
An equilibrium which is present in all water and aqueous solutions.
What are the naturalization equations?
Acid+alkali>salt +water
Acid+metal oxide>salt +water
How can you make a salt from a n insoluble metal carbonate?
A titration experiment can be carried out to accurately measure the volume of substances that react in chemical equations this is often used to calculate an unknown concentration.
What are the steps in a Titration?
What is the triangle for calculating mass, GFM (formula mass) and number of moles?
What is the triangle for calculating concentration, number and volume
