The trial procedures. Part 1 is a acid value of juice when blending and sorting. More for less Fresh squeezed lemon, Orange, pineapple, 1.1 release coming to the water. 1.2. all 3 types of juices, bring mixture proportion: 1.2.1 apply pineapple juice to mix with lemon juice in 1 tbsp. 2.2 apply vinegar to the mixture with 1 tbsp lemon juice in equal quantities. 2.2 apply vinegar to the mixture with pineapple juice in equal quantities, 1 tbsp. 1.3 when mixing proportion. The people together, and then test the acid level up as I find with litmus. 1.4 notes that the trial results. Sort by level up as acid. From: less Step 2: learn the ability to eliminate corrosion stains on the coins. When the salt water mixture melts into it. The soluble salts that 2.1 has to be mixed with fruit juice in episode 1. In 1 tbsp 2.2 people together and he has a stain in the water soluble salt fruit. 2.3. about 30 minutes, then observe the changes that occur. 2.4 take coins out of clear water, dry thoroughly, compared with each other, and then save the results of an experiment that occurred.

Experimental procedure
at the first level of the acidity of the juice, when mixed and sorted from the
most to the least
1.1 lemon, orange, pineapple juice, leading to a
1.2. When all three kinds of juice, then mix together the following proportions
1.2.1. Pineapple juice mixed with 1 tablespoon lemon juice in equal quantities
1.2.2. Vinegar mixed with 1 tablespoon lemon juice in equal quantities
1.2.3. Vinegar mixed with 1 tablespoon of pineapple juice in equal
1.3. When mixed proportional ago. Stir well, then test the pH with litmus
1.4. The results are recorded By sorting the pH level. From the high to the low
in the second study, corrosion and stains on the coin. When salt water mixed into
2.1. The salt water was mixed with juice in the first volume in 1 tablespoon
2.2 Stir well and bring a medal dirt into the juice mixed with salt water for
2.3. Leave for 30 minutes and then observe the changes that occurred
2.4. Conduct Medal wash water. Wipe dry compared. Save Results The trial took place

Trial procedures
when 1 study the acidity of the juice when mixed and sort out the
high to less
1.1 the lemon. Orange, pineapple, juice to water
1.2 when both 3 juice type. Then mixed according to proportion as follows:
1.2.1 the pineapple juice mixed with lemonade. In 1 tablespoon same
1.2.2 brought vinegar mixed with lemonade. ในปริมาณ 1 eruptions เท่ากัน
1.2 in can3 นำ น้ำส้ม ไป ผสม กับ Bahamian EOS ในปริมาณ 1 eruptions เท่ากัน
1.3 เมื่อ นำไป ผสม ตาม สัดส่วน แล้ว EOS คนให้ เข้ากัน แล้ว price หา ระดับ ค่า ความเป็นกรด ด้วย กระดาษลิตมัส sb 1.4 recording experiments. By sorting the pH from the high to low
when 2 study can in corrosion and stains on the coins. When the salt water mixed
2.1 to the salt water to mix with juice when 1 in 1 tablespoon
2.2 stir. The coins with the dirt into juice mixed salt water
