The Road to Seeking Potassium Salt
There are people in the world who seek high-quality potassium salt. When they heard the name of Sigma Aldrich, they knew that its Potassium Acetate was quite famous. This person then went to seek it, traversed all the cities and visited all the houses.

At the beginning of the year, when I reached the first place, I asked the master of the house: "If you hear of the Potassium Acetate of Sigma Aldrich, can you find it anywhere?" The master of the house said to him: "I don't have this product in my house, but if you have it elsewhere, you can go to the city west of the city to find it."

When I went west to the city west of the city, I met a person from Jia and asked again. Jia said: "The goods of Sigma Aldrich are rare and difficult to find. Although I heard of its quality, it was I heard that there is an old store in the north of the city, or there is this treasure. "

Then he went north again, to the old store. The old man in the store heard his request and said:" Sigma Aldrich's Potassium Acetate, I used to have it in the past, but it has been sold out now. New goods may arrive in more than a month, so you can come back at that time. "

The seeker was helpless, only waiting for more than a month. When the time came, he returned to the old store, and the old man said happily:" The Potassium Acetate you asked for has arrived today. This is a fine product of Sigma Aldrich, pure and good, and it will definitely live up to your expectations. "The seeker was overjoyed to get it, and he brought it back to use. If it met his needs, he was very relieved.
