Document Summary
Acids and bases: both are electrolytes, ionize and dissociate in water, acids are proton donors, release h+ (a bare proton) in solution, hcl h+ + cl . Take up h+ from solution: naoh na+ + oh , oh accepts an available proton (h+, oh + h+ h2o. T [h+], ph: acidic ph: 0 6. 99, neutral solutions, equal numbers of h+ and oh , all neutral solutions are ph 7, pure water is ph neutral, ph of pure water = ph 7: [h+] = 10 7 m. Neutralization: results from mixing acids and bases, displacement reactions occur forming water and a salt, neutralization reaction, joining of h+ and oh to form water neutralizes solution. Acid-base homeostasis: ph change interferes with cell function and may damage living tissue, even slight change in ph can be fatal, ph is regulated by kidneys, lungs, and chemical buffers.
