What is the role of pH in dialy life

Answer 1

The stomach secretes hcl to kill bacteria and digest food without harming the stomach. during indigestion stomach produces too much acid and causes pain and irritaion. to get rid of this we use bases called antacids.eg: milk of magnesia. plants require a specific range of ph for their healty growth. human body works in ph range of 7.0 to 7.8 when ph of rainwater is less than 5.6, it is acid rain.it damages aquatic life , monuments..... lower ph because of sweet and sour food can cause toooth decay.ph of mouth should be more than 5.5.to prevent this we use tooth pastes that are basic in nature certain animals like bee and plants like neetle secrete highly acidic substance for self defence.use of a mild base like baking soda gives relief.
