Carboxylic Acids Flashcards
(17 cards)
What series are carboxylic acids part of
The homologous series
What’s the name of the carboxylic acid functional group
Carboxylic functional group -COOH
What’s the general formula for carboxylic acids
CnH2n+1COOH
Name 3 uses for carboxylic acids
- To make preservatives
- Soaps
- Medicines
Why is vinegar (ethanoic acid CH3COOH) used for cleaning
Because it’s non-toxic snd therefore safe to use in your home
As the size of carboxylic acids increases what happens to the melting and boiling points
The melting and boiling points increase
The first forum carboxylic acids are miscible in water, what happens to the solubility of these acids as the size increases?
They become less and less soluble
What is the pH of a carboxylic acid?
Less than 7
What do carboxylic acids react to form?
Salts
What is the word equation for a carboxylic acid reacting with a metal carbonate?
Carboxylic acid + metal carbonate —> salt + water + carbon dioxide
What is the word equation for carboxylic acid reacting with metal?
Carboxylic acid + metal —> salt + hydrogen
What is the word equation for a carboxylic acid reacting with metal oxide and hydroxide?
Carboxylic acid + metal oxide + metal hydroxide —> salt + water
example, if ethanoic acid reacts with sodium carbonate, what will it produce?
Sodium ethanoate + water + carbon dioxide
How do you name a salt?
- The first part of the name comes from the metal ion in the salt.
- The second part of the name comes from the carboxylic acid and ends in -anoate
{for example, ethanoic acid and magnesium carbonate will form the salt magnesium ethanoate}
If ethanoic acid reacts with magnesium, what will it produce?
Magnesium ethanoate + hydrogen
If propanoic acid reacts with sodium oxide, what will it produce?
Sodium propanoate + water
What’s the ending for a carboxylic acid?
-oic acid
