Salt + water |
|
|
|
Acid+Carbonate |

|
|
|
Neutralisation meaning |
Produce water + salt = Acid + base & carbonate |
|
|
|
Strong bases produce ....(g) when heated with ammonium compounds. |
Ammonia |
|
|
|
Why do we control soil acidity? And how? |
Because crop grow best in pH near 7 Limestone, lime, slaked lime Calcium (carbonate, oxide, hydroxide) |
|
|
|

|
|
|
Salt from metal, carbonate and insoluble base process |
1. Dissolve 2. Filter 3. Evaporate 🔮🔮 (Need to filter because we poured extra) |
|
|
|
Salt from soluble base/alkali process |
Titration 1. Pour acid to alkali (burette) till indicator (to know if it's been neutralize) is colourless 2. Measure how much acid in step 1 3. Repeat without indicator (impurities) 4. Evaporate 🔮🔮🔮 (No need to filter because there aren't any excess) #step 1 |
|
|
|
Salt can be made by ....+acid |
Metal, in/soluble base, carbonate |
|
|
|

High conductivity Low pH Hydrochloric acid Sulfuric acid Nitric acid |
Opposite |
|
|
Weak acid meaning and example |
Low conductivity Higher pH Methanoic acid Ethanoic acid Citric acid |
Opposite |
|
|
Strong alkalis |
High conductivity High pH Sodium hydroxide Potasium Hydroxide |
|
|
|
Weak alkalis |
Low conductivity Low pH Ammonia solution |
|
|
|
Metal + acid is redox because....? |
There's a displacement |
|
|
|
How does neutralisation work? |
It works because two of the ions form water (H and O) and the rest makes the salt (and carbon dioxide) HCL+NaOH=H2O+NaCl H+ Cl- + Na+ OH- =H+OH. +. NaCl =H2O + NaCl |
|
|
|
Protons are.... By acids |
Released (Hydrogen doesn't have electrons so it gives the proton instead) |
|
|
|
Protons are.... By base |
Accepted |
|
|
|
