In addition, there will be a trial of Abbots correspondent, acid-bass is the value of the acid-bass or the formation of acid pH - bass by using Abbots correspondent, and Abbots correspondent, the study found that when there is a variety ofBut Abbots correspondent, the most frequently used option is because it can be observed the paper ลิตมัส is easy and cheap and there are two colors, blue or blue and red or pink color, but could not verify that aqueous acid-bass is pHYou can say that it is an acid or bass, from the study partners won ลิตมัส paper information can be extracted from natural substances, but there will be a limited range of change color.The pH aqueous acid-bass settings to a variety of options to choose to use Abbots correspondent, by using substances extracted from plants flower in Sri District of Sukhothai Province, darts, 5 types of needle อัญชัญ flower red flower cape marigold flower primrose willow, purpleAs the study found that these substances extracted from plants can be used as a check of Abbots correspondent, is an acid-bass because it is a substance, called the recycling of strychnine (anthocyanins) is the object or color (pigment) to the red and blue purpleThe recycling of the strychnine can be dissolved in water, is not stable, damage, is easy with the heat oxygen structure when the light changes color to change to a factor that has an effect on the color of the recycling of the strychnine is an acid alkaline when pHWhen pH Up will change to Blue, Red needle flower flower flower อัญชัญ primrose willow, purple and blue flowers to boom can check the acid-bass is the African marigold flower substance known inexpensive vehicle, shopping etc (carotenoid) to the object (pigment).Red Orange and orange-red plant found in general, the acid and bass, it is a factor that makes the color of inexpensive vehicle, shopping etc to change the 5 types of plants can be monitored during the pH.pH 1-14, red flower needle to change the color settings in the pH = 6 - 8 the butterfly pea flowers change color settings in the pH = 1 - 4 cape marigold flowers change color settings in the pH = 9 - 10 flower primrose willow, purple color changes in the pH= 1-2, a flower and flower festoons blue color changing settings in the pH= 1-2,12 - 14 and 5 kinds of plants, this is a easy-to-crop farming has many easy-to-grow fast to the drought-resistant flowers throughout the year and also has a nice color that will make the study by leading crop, 5 this type of juice with water.5 the proportion of pre-defined by each time that will be mixed with aqueous hydrochloric acid to test the performance, hydrochloric acid and NaOH solution for bass is Sodium Hydroxide or caustic soda will be set pH from 1 - 14When pH has accounted for the best performance, and make the collection analysis provided for color bar to tell the pH pH value compared to change the color of juice.
