What can he conclude about the pH of each sample?

What can be concluded about the pH of glass cleaner, aspirin, and sugar water samples? Glass cleaner, containing ammonia, is likely to be basic due to a high pH value. Aspirin tends to be acidic with a pH value below 7. Sugar water, being mostly water, should have a pH value around 7, making it neutral.

Understanding pH Levels:

pH is a measurement of how acidic or basic a substance is on a scale of 0 to 14. A pH value of 7 is considered neutral, below 7 is acidic, and above 7 is basic. In this scenario, the individual can conclude the pH levels of the samples based on their properties.

Glass Cleaner:

Based on the presence of ammonia, a common basic ingredient, in glass cleaners, it can be inferred that the glass cleaner will have a high pH value above 7, making it basic. The strong basic nature of ammonia contributes to the alkalinity of the glass cleaner, making it effective in cleaning glass surfaces.

Aspirin:

Aspirin is known to have acidic properties and is commonly used as a pain reliever. Due to its acidic nature, aspirin is expected to have a pH value below 7. The acidity of aspirin can sometimes cause irritation in the stomach when consumed in higher doses.

Sugar Water:

Sugar water, being primarily composed of water, is expected to have a pH value around 7, which is considered neutral. The dissolved sugar in water does not significantly alter the neutral pH of water, making sugar water a neutral solution. This is why sugar water is often used as a simple solution for hydration and sweetness.

These conclusions highlight the importance of understanding pH levels in different substances and how they can impact their properties and interactions with other substances.
