Chem Literacy Flashcards
Define an acid
Hydrogen ion/ proton donor
Describe the structure of a protein
Chain of amino acids
Fold to give a 3D structure
Suggest why dental enamel is so strong
Held in an ionic lattice
Tough structure
What does solvated mean?
Associated with a solvent molecule.
Form ion dipole electrostatic attraction
Not a complex ion
Why do acidic conditions cause calcium phosphate hydroxylapatite to become solvated?
Increase attraction of ions into aqueous solution
What does supersaturated mean?
Contains as much ions as possible.
Max concentration of ions
Formula for calcium phosphate
Ca3(PO4)2
What functional groups are present in lactic acid
Alcohol
Carboxylic acid
Define a strong acid
Fully dissociates into its ions
What type of isomer is seen in dectaflur
Trans isomer
What is protolysis?
Proton transferring reaction
What is the ion product?
Product of conc of ions in solution raised to the power of their stoichiometry
What happens if IP> Ksp
Precipitate will form
How to calculate supersaturation?
What’s the SS of calcium fluoride?
IP/Ksp rooted to the power of the M units
CaF2- 13.2
Stoichiometry and substoichiometry
Stoichiometry- ratio of moles
Substoichiometry- involves less than the stoichiometric amount of reagent
