Which pH value indicates an acidic solution?
The pH scale is a measure of how acidic or basic a solution is. A pH value below 7 indicates an acidic solution. The lower the pH value, the more acidic the solution is.
Acidic solutions have a pH range from 0 to 6.9 on the pH scale. A neutral solution, such as pure water, has a pH of 7. Basic solutions have a pH range from 7.1 to 14 on the pH scale. pH values below 7 indicate acidity, while pH values above 7 indicate alkalinity.
What is the pH value of lemon juice?
Lemon juice has a pH value of around 2, making it highly acidic.
What is the pH value of vinegar?
Vinegar typically has a pH value between 2 and 3, indicating that it is also highly acidic.
What is the pH value of orange juice?
Orange juice has a pH value of around 3.5, making it slightly less acidic than lemon juice but still acidic.
What is the pH value of soda?
Soda has a pH value of around 2.5 to 3, making it acidic due to the added citric and phosphoric acids.
What is the pH value of tomato juice?
Tomato juice has a pH value of around 4, indicating that it is mildly acidic.
What is the pH value of coffee?
Coffee typically has a pH value between 4.5 and 5, making it slightly acidic.
What is the pH value of milk?
Milk has a pH value of around 6.5 to 6.7, making it slightly acidic but closer to neutral.
What is the pH value of battery acid?
Battery acid, also known as sulfuric acid, has a pH value of around 0, indicating extreme acidity.
What is the pH value of stomach acid?
Stomach acid, or hydrochloric acid, has a pH value of around 1.5 to 3.5, making it highly acidic.
What is the pH value of rainwater?
Pure rainwater has a pH value of around 5.6 due to the presence of carbon dioxide, making it slightly acidic.
What is the pH value of bleach?
Bleach has a pH value of around 12 to 13, indicating that it is highly alkaline.
What is the pH value of baking soda?
Baking soda, or sodium bicarbonate, has a pH value of around 8.3, making it slightly alkaline.
The pH value of a solution plays a crucial role in determining its properties and interactions with other substances. Understanding the pH scale and its implications can help in various fields, from chemistry to everyday household tasks. Remember, a pH value below 7 indicates an acidic solution, while a pH value above 7 indicates a basic solution.
