- Acid, Base and pH
- Definintion
- Acid: proton donor
- Base: proton acceptor
- pH: measure of hydrogen ion in a solution.
- Bronsted-lowry definition
- Acid: donate a proton
- Base: accept a proton
- Testing pH
- Strong acids e.g HCl
- Fully dissociate
- Weak acids e.g Ethanoic acid
- Partly dissociate
- Low(H+)= high pHHigh(H+)= low pH
- Calculating pH
- pH= -log(H+)or(H+)= 10-pH
- Logarithmic constant pKa= -logka and ka= 10-pka
- Strong acids e.g HCl
- Remember:-monobasic = donates 1 hydrogen per molecule-dibasic = donates 2 hydrogen per molecule etc....
