Know some interesting facts about pH & pH scale in chemistry tuition

Learn what is pH & pH scale in chemistry tuition

 

 

pH measures the concentration of the hydrogen ions, alkalinity or acidity of a given solution. It is a vital quantity which reflects a solution's chemical conditions. The pH controls the availability of biological functions, nutrients & behavior of chemicals. There are so many unknown facts about pH which students do not know. If you want to learn such unbeatable facts, then contact one of the best chemistry learning centres offering chemistry tuition in Singapore.

 

 

 

Understand the Definition of pH in chemistry tuitions:

 

What is the full form of pH? "Potential of Hydrogen" is the full form of pH. pH measures the basicity or acidity of a solution. You can measure pH value with the help of a pH scale. The pH scales usually range from 0 to 14 in the water. The solutions which carry pH values from 0 - 7 come under acidic states and from 8 - 14 under basic states. pH holds importance in chemistry, biology, water purification and many science-related activities. If you face challenges in understanding pH concepts, join Chemistry Tuition in Singapore.

 

How to measure the pH of a solution?

 

Litmus paper or litmus solution helps in determining whether the particular solution is basic or acidic. While measuring two acidic solutions which contain varying amounts of acids can not be measured properly. The issue can be solved if you use the scale called "pH scale". If you want to learn o Level chemistry, contact a reliable learning centre which provides O Level Chemistry Tuition in Singapore.

 

Who has discovered the pH Scale? 

 

In 1909, the pH scale was introduced by S.P.L. Sorensen. The pH of any solution can tell you which one is more basic or acidic than the other.

 

Understand pH of Acids & bases in chemistry tuition:

 

You can have a look at these points to know more about pH:

 

a) Learn in chemistry tuition about Neutral substances having 7 pH

 

The neutral solutions have a pH of 7. For example - water is a common neutral substance. The solutions which have a pH of 7 will not have any effect on a litmus paper or other indicators like phenolphthalein etc. 

 

b) Acids have less than 7 pH

 

Substances having a pH less than 7 are acidic. Suppose we take a solution having a pH of 5 that will be acidic. The solution having a pH of 2 will be more acidic than the solution having a pH of 5. The solutions having a pH of 1 to 3 are considered strong acids. The solutions having a pH from 4 to 6 are known as weak acid solutions. These solutions transform the colour of blue litmus paper into red.

 

c) Base solutions have more than 7 pH

 

The base solutions have a pH of more than 7. The solutions which have pH values from 8 to 10 are generally considered weak bases, whereas solutions having pH values from 11 to 14 are considered strong bases. These solutions turn red litmus blue.

 

We strongly hope that this blog regarding pH has been helpful to you. Chemistry is an interesting subject if you understand the concepts well. With regular practice and learning chemistry, the subject can be lovable. Students may have some queries, for that, you need to engage with learning centres providing O Level Chemistry Tuition in Singapore .
