Unlocking the acidity levels of various substances has never been more straightforward, thanks to the LaMotte Acidity Test Kit – 7182-01. Designed for accuracy and ease of use, this kit equips you with everything necessary to determine the concentration of hydrochloric, sulfuric, and phosphoric acids economically. Let’s delve into how this kit simplifies the acidity testing process.
Contents:
- Sodium Hydroxide, 2.4N – 30mL
- Phenolphthalein Indicator, 0.5% – 15mL
- Pipet, 0.5mL, plastic
- Test tube, 5-10-25mL, plastic with cap
Utilizing the phenolphthalein endpoint method, this kit offers a range where 1 drop equals 0.1 or 1.0% (as the specific acid). With 50 tests available at 10% (2), it ensures multiple uses before replenishment. Here’s a step-by-step guide on how to conduct the test:
Test Procedure (1 drop = 0.1%):
- Fill the test tube (0715) to the 5mL line with the sample.
- Add one drop of Phenolphthalein Indicator, 0.5% (2258) and mix.
- While gently swirling the tube, add Sodium Hydroxide, 2.4N (5648) one drop at a time until the solution turns pink. Count the number of drops added. Ensure the bottle is held vertically.
- Multiply the number of drops used in Step 3 by 0.1 to obtain the % Phosphoric Acid or Sulfuric Acid. For % Hydrochloric Acid, multiply the number of drops used in Step 3 by 0.076.
Test Procedure (1 drop = 1%):
- Utilize the 0.5 mL pipet (0353) to add 0.5 mL of the sample to the test tube (0715).
- Dilute the sample to the 5 mL line with tap water.
- Add one drop of Phenolphthalein Indicator, 0.5% (2258) and mix.
- While gently swirling the tube, add Sodium Hydroxide, 2.4N (5648) one drop at a time until the solution turns pink. Count the number of drops added, ensuring the bottle is held vertically.
- Multiply the number of drops used in Step 4 by 1 to obtain the % Phosphoric Acid or Sulfuric Acid. For % Hydrochloric Acid, multiply the number of drops used in Step 3 by 0.76.
It’s important to note that the LaMotte Acidity Test Kit has a minimum order quantity of 2 kits. Additionally, here are the specifications:
