WHAT IS pH? HOW IT IS DETERMINED? WHAT ARE ITS STANDARDS IN WASHING POWDER

In this video I tell you about pH. WHAT IS pH? HOW IT IS DETERMINED? WHAT ARE ITS STANDARDS IN WASHING POWDER
pH is basically a parametre the test of alkaline and acidity check in a water and solution.
In this video we check two samples of different brands of washing powder practically. For this purpose we use different type of pH paper but not all of them effective. I recommend two types of pH meters that shown in video.
Now I explain you step by step
1.First we take 1 gram of washing powder.
2.Then we add 100 milliliter water in it.
3.Then we mix it with the help of magnetic sterior(produce heat because of its heaters and mix well).
4.when it mix properly our washing powder sample is ready to check its pH.
5.The pH of our first sample is about 10 from Ph paper and 10.3 from pH meter.
