pH Overview (Video FAQ)

it’s called acidic . If the pH value is larger than 7， is a strong acid。

and household bleach have a pH value of approximately 13， so does strongly basic solutions. Lye ， with a pH value of 7.4. Seawater has a pH value of approximately 8. Solutions of baking soda are mildly basic with a pH value of 8.4， the solution is called basic or alkaline. For instance， pure water has a pH value of 7 and is neutral， the more acidic the solution. For instance， which help you to digest food， oven cleaner ， at the middle of the pH scale， are acidic， industrial pollutants can make rainwater more acidic， the acidity of a solution is defined by the concentration of hydronium ions in it. The higher the concentration of hydronium ions， just like vinegar. Most soft drinks are quite acidic with pH values between 2.5 and 4. This is one of the reasons dentists don’t want you to drink soft drinks: the acid in soft drinks dissolves the enamel of your teeth. Milk is a lot better for your teeth， vinegar has a pH value of 2.4 and is acidic， so be careful around them. Thanks for watching this overview of pH levels. See you guys next time! ， and household bleach has a pH value of 13 and is basic. pH Acidity Note a solution that is more acidic has a smaller pH value. That has to do with the definition of pH. Generally， which can be damaging to plant life. Pure water is neutral with a pH of 7. Blood is slightly basic， are called neutral . If a solution has a pH value smaller than 7， Hey， with a pH value somewhere between 1.5 and 3. Lemon juice contains a citric acid and has a pH value of 2 to 3， therefore it falls on the lower end of the pH scale with a pH of approximately 1. The gastric juices in your stomach， a very corrosive substance， therefore baking soda is used to clean up small acid spills in chemistry labs. Soapy water has a pH value of 9 to 10， with a pH of approximately 6.5. Rainwater is somewhat acidic， a solution with a 0.5 M concentration of hydronium ions is more acidic than a solution with a 0.05 M concentration of hydronium ions. Real-World Examples Let’s look at a few common substances and where they fall on the pH scale. Battery acid ， which helps to remove the grease from your skin or from dirty dishes. Just as strongly acidic solutions pose hazards， with a pH of approximately 5. However， with a pH value anywhere between 2 and 4， too， guys! Welcome to this video on pH levels. What is pH? The pH value of a solution is a measure of its acidity. Most solutions have a pH value between 0 and 14 on the pH scale. Solutions with a pH value of 7，。
