Physics: Acids and Bases are Everywhere
Every solution has either has an acid or basic trait. The acid or basic trait in a solution are called pH level. pH is a scale that is used to determine if solution is acidic ,basic, or neutral. During Living Environment class, we conducted a experiment that allowed us to measure the pH levels of 3 solutions. We were split into groups and each person had to bring a household solution from around the house. There certain materials that were needed to conduct the experiment .The following materials are litmus papers, pH paper, pH indicator, a sheet of paper towel and a dropper. The household solutions that my group brought were nail polish remover, vinegar, and water. Then we would lay the three litmus papers and three pH papers space them away from each other. After that, a person my group would take the dropper and put drops of each solution on the three litmus papers and the three pH papers. There are solutions which have the property of changing their color when they come in contact with an acidic or basic environment. An example of this was vinegar, when it contact the litmus and the pH paper, it became red. Then ,we check the pH indicator and find out that vinegar was acidic on both paper ,also , that the pH level was 2.4.Also the same thing happen with the water and nail polish remover. The color it became when it contact the paper was dark blue, which is basic ,and the pH level is 10.9. The water turn green on the litmus and pH paper when it contact the paper, which is neutral, and the pH level is 7. With these experiments, you saw that there are acid substances , basic substances, and, neutral substances. All solutions are one of these . Finding the pH level is an easy and educational

The strength of an acid or base is measured on the pH scale. The term “pH” is short for “potential of hydrogen.” It is a measure of how many excess H+ ions there are in a solution. The pH scale runs from 0 to 14, with 0 representing the highest concentration of hydrogen ions. Acidic substances have a pH below 7, while alkaline substances (bases) have a pH above 7. Pure water has a pH of 7 and is considered neutral.…

For thousands of years, people have known lemon juice, vinegar, and many other foods taste sour. However, it was not until a few hundred years ago that it was discovered that these foods tasted this way because they were all acids. In the seventeenth century, the Irish writer and amateur chemist Robert Boyle first labeled substances as either acids or bases. He noted that acids tasted sour, are corrosive to metals, change litmus red, and become less acidic when mixed with bases. On the contrary, bases felt slippery, changed litmus blue, and became less basic when mixed with acids. In the late 1800s, the Swedish scientist Svante Arrhenius believed that acids are compounds that contain hydrogen and can dissolve in water to release hydrogen and can dissolve in water to release hydrogen ions into solution. He also defined bases as substances that dissolve in water to release hydroxide ions into solution. Finally, in 1923, the Danish scientist Johannes Bronsted and the Englishman Thomas Lowry altered Arrhenuis’ theory slightly, saying acids and bases are substances that are capable of splitting off or taking up hydrogen ions respectively. In 1909, the Danish biochemist Sören Sörensen invented the pH scale for measuring acidity. The pH scale ranges from 0 to 14, where substances with a pH between 0 and less than 7 are acids, substances with a pH greater than 7 and up to 14 are bases, and a substance is considered neutral when they have a pH level of 7.…

The pH Scale is a scale made to show how acidic or alkaline a substance is. The pH of something is measured with pH paper which can vary from wide range paper, which covers all ph’s, but is not as accurate at some others. There are pH papers that get very specific that can have a range such as 2 or 3 and get much more precise. The neutral on the scale is 7. Anything that is below 7 is considered acidic and anything above 7 is considered alkaline. Acidic substances contain more H+ than OH-. H+ stands for a positively charged hydrogen ion and OH- stands means a negatively charged hydroxide ion. This means something with the pH level of 4 is more acidic than something with the pH level of 9.…

As we all know every solution is either acid or alkaline. Alkaline is often called base. These solutions can be anything from body fluids, to fruits, vegetables, seawater, beverages you name it. Acid and alkaline is measured in pH. It starts as low as zero being very acidic and works its way up to fourteen being the most basic. The pH of our stomach is 2, obviously to digest food, wine is 3.5,water is 7(neutral), arterial blood is 7.4, and seawater is 8.5. Baking soda is 12.…

The pH scale measures how acidic or basic a substance is; It ranges from 0 to 14. A pH of 7 is neutral, less than 7 is acidic, and a pH greater than 7 is basic. The PH scale is summarized by two main categories. Acids release Hydrogen ions while Bases release hydroxyl ions. The higher the hydrogen ion concentration the more acidic the solution. A Neutral PH is considered to be a 7, on a scale from 0 to 14. Acidic is on the low end of the scale while basic is on the high end of the scale. The PH scale is very important in living cells and tissues because everything inside the body has an “optimal PH”. This means that certain reactions cannot occur or are not as effective if the PH isn’t correct.

Every liquid you see will probably have either acidic or basic traits. Water (H2O) can be both an acid and a base, depending on how you look at it. It can be considered an acid in some reactions and a base in others. Water can even react with itself to form acids and bases. It happens in really small amounts, so it won't change your experiments at all. It goes like this:…

The pH is a number showing the amount of hydrogen ions in a solution. pH stands for Potential Hydrogen. The scale ranges from 0-14. Something with a pH level of 7 is totally neutral, neither acidic or basic. A pH level lower than 3 can give brain damage to people. The pH is expressed as moles of hydrogen ions per liter.
