WebHow does pH affect H concentration? Hydrogen Ion Concentration (pH) A pH of 7 is neutral. A decrease in pH below 7 shows an increase in acidity (hydrogen ions), while an increase in pH above 7 shows an increase in alkalinity (hydroxyl ions). Each pH unit represents a 10-fold change in concentration. Web21 feb. 2024 · Your stomach secretes hydrochloric acid, but the pH of your stomach isn't necessarily the same as the pH of the acid. The pH of your stomach varies, but its natural state is between 1.5 and 3.5. 1 This level rises when food enters the stomach; it can reach up to six, but it lowers again throughout digestion as stomach acid is secreted. 2
