What is one example of acid and one of bases?
Car battery acid, bleach
What do acids do that bases don’t?
Sting on a wound, taste sour, turns litmus red and the PH is less than 7
What do bases do that acids don’t?
Feels slippery, tastes bitter, turns litmus blue, The PH is more than 7
What does PH mean?
Power of hydrogen
when the PH scale goes down by one how much does its power change? (how much is it multiplied by?)
10
What does PH measure?
The concentration of hydrogen ions in a solution
What is an acid that is almost at a PH scale of 0?
Battery acid
What is a base that is at a PH scale of 14?
drain cleaner
What is a neutral solution?
human blood
Acid rain occurs when?
Acidic gases enter the atmosphere and when it rains the acid gets pulled down, decreasing the PH
why does acid rain occur along the east coast of North America?
The wind patterns carrying acidic chemicals to the east coasts
Bases being used to neutralise acid contents is called what?
acid-base neutralisation
The process of what is when planes drop calcium carbonate into lakes to help increase or normalise the PH levels?
The process of Liming
What does a catalytic converter do in a vehicles?
They limit the amount of nitrogen oxide
what does a scrubber do in factories?
They use a sorbent to capture and absorb harmful oxide sources to reduce emissions
