What Is the Ph of a 2.3 M Oh Solution

Understanding pH Levels

Acids and bases are two important concepts in chemistry. To really understand the difference between acids and bases, it's essential to understand what pH is. Learn more about pH levels and what they mean for you in your day-to-day life with this simple guide.

Acids and Bases

Put simply, pH levels are simply a chemical measurement of how acidic or basic a substance is. Instructional pH scales often show a range of different recognizable things to put this in context. The scale of pH levels runs from zero to 14, with highly acidic things like battery acid sitting closer to zero than highly basic things like lye, which sit closer to 14. Substances like milk are closer to the middle of the scale. As you can tell, the extremes of the scale are usually reserved for substances that can be harmful.

Is There Such Thing as Bad pH Levels?

Can a pH level be bad? Potentially. If something is measuring at a higher or lower pH than it should, that could be a sign that something's off. It's possible to test pH in a number of ways, from test strips to homemade experiments with purple cabbage, in case there's a situation in which you need to know the pH level of a substance.

The pH of Water

The pH scale makes it seem like just about any substance can be easily placed on a continuum of zero to 14, but that's not necessarily true. Water, for example, has a pH of seven in its purest form, which puts it smack in the middle of the scale. This may make it seem like water should be the most neutral substance on the planet, but it isn't necessarily the case. Water can naturally occur with contaminants that change its pH level. In fact, rainwater in different areas can have different pH, according to the US Geological Survey, with deviations of more than a full point possible in different parts of the USA. That shows how water can be more or less acidic under different conditions.

How pH Affects Your Life

In most contexts, pH is seen as a topic for discussion in scientific research or education. You don't necessarily need to actively worry about monitoring the pH of what you eat and things like that. However, pH can be used as a marketing tool, and it's important to understand what it means in this context.

pH in Product Marketing

Some products, particularly beauty products like facial cleansers or shampoos, may tout themselves as "pH balanced," but what does this mean? What is your pH balance and why does it relate to face wash? There are ways in which this claim can be nothing more than marketing jargon, but it turns out that skin does have an ideal pH level. Soaps tend to be heavily alkaline, meaning they have a high pH. However, the skin has a natural acidity, with a pH level of around 5.5. A pH neutral cleanser will use less alkaline or basic ingredients to help keep your skin in balance.
