WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. Image modified from " Water: Figure 7 ," by OpenStax College, Biology, CC BY 4.0. Modification of work by Edward Stevens.

WebMar 4, 2016 · Starsan has two active ingredients: Dodecylbenzenesulfonic acid (DDBSA) and Phosphoric acid (PA). Their concentration in straight starsan is 15% and 50% respectively. This means that for every mL of starsan there is 150 mg of DDBSA and 500 mg of PA. WebThe reaction temperature should not be allowed to exceed 50°C and the pH should not go below 6.5. Approximate amounts of BIO -SOFT S-101 and various alkalies for … The biodegradability of alkylbenzene sulfonates has been well studied, and is affected by isomerization, in this case, branching. The salt of the linear material has an LD50 of 2.3 mg/liter for fish, about four times more toxic than the branched compound; however the linear compound biodegrades far more quickly, making it the safer choice over time. It is biodegraded rapidly under aerobic conditions with a half-life of approximately 1–3 weeks; oxidative degradation initiates at t… can leo and aquarius be friends
