Classify the liquids that she has consumed as acidic or alkaline.
A 55-year-old woman orders a cheese and bacon pizza with extra cheese and has about 3 large glasses of cola (ph value 3). On the way back home, she experiences heartburn and abdominal pain, and has difficulty breathing. She drinks a lot of water and has to consume milk of magnesia (ph value 10.5) before she feels comfortable again. Classify the liquids that she has consumed as acidic or alkaline, state the ph values of water and blood, and state what the patient can include and avoid in her diet on a regular basis to avoid these symptoms in the future.
The pH value tells us about the acidity or basicity of a solution. Acids have a pH values less than 7 while bases have a pH greater than 7. Pure water has a neutral pH of 7. Tap water is likely to have a pH above or below 7 depending on the water in your area.
The cola, which as a pH of 3, is acidic. While our stomachs contain gastric acid (pH is ~2) eating foods that are high in acid or lots of acidic foods can lower this pH to a point that creates abdominal discomfort and/or heartburn. The milk of magnesia has a high pH which is a basic solution. Consuming the milk of magnesia will neutralize the excess acid. Blood is close to neutral at a pH of 7.4 and the body can tolerate only small changes in pH.
