Review: Homeschool Science Item - I needed this item to get through an experiment that was in my daughters 8th grade science curriculum. I was worried that this may not work as intended since I don't know the quality, however I was very happy with this item and the science experiment worked as intended. I also have plenty to use if it's needed in the future. The seller did a great job of prepping it for shipping, it can without any leaking or issue. Review: Perfect for spot checking spa pH - This pH solution makes checking spa pH super easy! Instead of messing with comparators, I just drop a few drops right in the spa. As long as the drops stay blue, the pH is fine. Anyone who works with spas routinely knows that it's hard to get the pH too high, but the pH being too low is where the problems start. Highly recommend this solution! ## Features - 30mL bottle of bromothymol blue - Chemical for general purpose lab and educational use - Used as a pH indicator - Perfect for use in any chemistry lab or classroom - Includes directions for safe storage and SDS is available on product page and by request ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07JCF57G3 | | Best Sellers Rank | #76,086 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #50 in Aqueous Solutions | | Date First Available | October 12, 2018 | | Is Discontinued By Manufacturer | No | | Item Form | Liquid | | Item Weight | 1.44 ounces | | Item model number | IS11073 | | Manufacturer | Innovating Science | | Package Dimensions | 4.29 x 2.28 x 1.38 inches | | UPC | 724832003984 | ## Product Details - **Brand:** ALDON - **Item Volume:** 30 Milliliters - **Item Weight:** 0.09 Pounds - **Package Information:** Bottle - **Percentage assay:** 0.5 ## Images ![- 0.5% Bromothymol Blue Solution, 30mL - The Curated Chemical Collection - Image 1](https://m.media-amazon.com/images/I/51i1bhqtIzL.jpg) ## Questions & Answers **Q: What is the working concentration of this?** A: 99.5% water, .5% bomothymol blue, sodium salt ## Customer Reviews ### ⭐⭐⭐⭐⭐ Homeschool Science Item *by P***M on September 23, 2023* I needed this item to get through an experiment that was in my daughters 8th grade science curriculum.

Highly recommend this solution! ### ⭐⭐⭐⭐ Worked, but Not What I Expected *by W***Y on March 29, 2025* It worked fine, but it wasn’t quite what I expected. The color change was noticeable, but the solution didn’t behave the way I thought it would in my experiments. It’s definitely functional, just a bit different from what I imagined. Not bad, just didn’t meet all my expectations. ## Frequently Bought Together - ALDON Innovating Science 0.5% Bromothymol Blue Solution, 30mL - The Curated Chemical Collection - Mannitol, Powder, Ultra Pure, Reagent, 4 oz.
