pH indicators

Acid solutions, have lower pH. Alkaline solutions, have higher pH. Substances that aren't acidic or alkaline (that is, neutral solutions) usually have a pH of 7. Acids have a pH that is less than 7. Alkalis have a pH that is greater than 7. 

Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically. pH is reported in "logarithmic units". Each number represents a 10-fold change in the acidity/basicness of the water. Water with a pH of five is ten times more acidic than water having a pH of six.

Baking Soda

Baking Soda is also known as Sodium Bicarbonate.Due to its abrasive and cleaning properties it is used as a raising agent in baking, as a household cleaner and in a number of other ways.

My Persuasive Writing

(Strawberry are the best fruit in the world)

Without a doubt strawberries are not the best fruit ever in the world.Everyone knows that there are lots of juicy,slushy and sweetest fruit in the world.Strawberries are sour,hard to grow and bad for some people.

Firstly,In the world there is lots of juicy,tastiest and slushy fruit. like  mango,kiwi,pineapple,pear etc. Strawberries are sour but not sweet.So how it can be the best fruit in the world?

Additionally, strawberries are hard to grow anywhere are any season.You have to work hardest and hardest to grow them.Sometime after working hard,you can't grow strawberries.

Finally,Strawberries are also bad for some people.There is also may contain pesticide residue.if you have heartburn, diarrhea, reflux, and bloating don't eat strawberries..

In conclusion, strawberry is not the best fruit in the world.There are also many juicy,slushy and tastiest fruit.so,I strongly believe that strawberries are not the bestest fruit ever.
