Initial Post Instructions While we often do not realize it, acidic and basic solutions are a part of our daily lives. Pick a solution in your home, work, or even outside (be sure to check the label to make sure that whatever you are measuring is nonhazardous and water based). Some possible solutions are shampoos, beverages, still water in your backyard, contact solution, etc. Research a compound or compounds found in your chosen solution, citing your sources in APA format and predict if the solution would be acidic or basic.

In our everyday lives, we are constantly exposed to different solutions with varying pH levels, which influence their acidity or alkalinity. One common household solution that is both safe and interesting to analyze is contact lens solution. This solution is designed to disinfect and store contact lenses, making it essential to understand its chemical properties, including its acidity or basicity.
Contact lens solutions typically contain a combination of disinfectants such as polyquaternium-1 and benzalkonium chloride, buffering agents like sodium borate and sodium boric acid, and other stabilizers. The primary function of these solutions is to maintain a pH that mimics natural tears, which is usually around 7.4, indicating a neutral to slightly basic pH. This pH range is crucial for comfortable lens wear and effective disinfection.
The buffering agents, especially sodium borate and sodium boric acid, play a significant role in maintaining the pH of the solution. Sodium borate, commonly known as borax, acts as a buffer and stabilizer, helping to maintain the pH around neutral to slightly alkaline levels. According to a study by Baker and Hopp (2018), borate-based buffers tend to have a pH in the range of 7 to 8, confirming their role in maintaining alkalinity in solutions.
Based on the chemical composition, it is predicted that contact lens solutions are generally basic (alkaline) with a pH around 7.4 to 8.0. This pH level ensures compatibility with the natural tears of the eye and supports the disinfectant activity of the solution. Maintenance of this pH also prevents irritation upon contact with the eye, which is essential for user comfort.
In conclusion, the primary compounds found in contact lens solutions, such as sodium borate, contribute to creating a slightly basic environment. This characteristic is critical for their disinfection efficacy and compatibility with the human eye. Scientific studies and ingredient labels confirm that these solutions tend to have an alkaline pH, emphasizing their role in maintaining ocular health and safety.
