What causes ingestion?
Excess HCl in the stomach
What are ingestion remedies
Metal carbonates, hydroxides or hydrogen carbonates which neutralise stomach acid
Give the reaction of Mg(OH)2, CaCO3 and NaHCO3 with HCl
Mg(OH)2 + 2HCl → MgCl2 + 2H2O
CaCO3 + 2HCl → CaCl2 + H2O + CO2
NaHCO3 + HCl → NaCl + H2O + CO2
What is the protective layer on the skin called ?
The acid mantle - Water and long chain carboxylic acids as well as lactic acids and amino acids. skin pH 4/5
What is the blood
Alkaline
What is the skins cleaning mechanism
Desquamation - mechanism by skin cells are shed
What can affect your skins natural pH
Age, stress, dust, pollutants
What are most soaps
