Feel the Significance of pH

pH Scale




Testing Methods


Meaning: The act of making a substance more dilute (less concentrated). The process of dilution treats acidic and basic substances by simply increasing the amount of the solvent compared to the amount of the solute. When diluting an acidic solution, the solution becomes less acidic and its pH level increases, approaching the pH level of 7 (neutral point). When diluting a basic solution, the solution becomes less basic and its pH level decreases, approaching the neutral point.

- Measures the pH level of a substance- Ranges from 0 to 14 with 7 being the neutral point- Anything above the neutral point is basic and anything below is acidicAcids (Acidic):- Ionic compounds that break apart in water to form a hydrogen ion (H+)- Corrosive (dissolve metals)- Sour tasting- Can be used to make fertilizer, refine petroleum, clean (usually found in kitchens), and process metalsBases (Basic):- Ionic compounds that break apart in water to form a negatively charged hydroxide ion (H-)- Slippery- Bitter tasting- Don't react to metals

Its effect on us and our environment:pH levels affect our surroundings greatly. From great lakes to rivers and oceans, if the pH level is too high or drastically low, wildlife is severly affected. Animals who depend on the water source for drinking to ones who live their day to day life in it, are killed every day or get severly poisoned including plants. Wildlife is not the only one in trouble. Us living beings are too. When the water we drink every day is too acidic or basic, we are in great danger. For example, when getting to our homes, the water has to pass through pipes. When the water itself is too acidic, the pipes get corroded leaving contaminants in our water. These contaminants can not only hurt us so bad to recieve diseases, but they can eventually kill us.


Meaning: The result of a neutral solution by mixing just the right amount of an acidic solution with a base. Neutralization treats acidic or basic solutions by adding its opposite together to reach the neutral pH level (7). When neutralizing an acid, the right amount of a base needs to be added to reach the pH level of 7 otherwise the entire substance will become too basic. The same process consists when neutralizing a basic solution. The right amount of an acid needs to be added to the solution to reach the neutral point otherwise the whole mixture will become too acidic.

Acids:- Vinegar- Dish Washer Ditergent- Orange Juice- Alcohol

Bases:- Ammonia- Baking Soda

Neutrals:- Water- Milk

Fun Facts:- Water's pH level is 6.5 - 8.5 - It's better for a substance to be more basic because acids have more dangeours/hazardous effects/are stronger in general- Our body is more basic- Acids and Bases affect everything from us to plants and animals- Alkali is another way to say Basic

There are multiple testing methods to identify the pH level of a substance:pH paper: When placed into the substance, it turns a color. The color can then be compared to a pH level chart where each different color represents a different pH level.Phenolphthalein: When a drop is placed in the substance, the color of the substance itself will either change purple, which means it's basic, otherwise it remains the same (the color it was before placing the indicator) meaning that the substance is either neutral or acidic (usually used for checking already gathered evidence).Universal Indicator: When a drop is placed into the substance, the color of the substance itself will turn a different color which will then be compared to an indicator chart which a certain color represents a range of pH levels.Other multiple tests that could be done but are extremely dangerous and many times avoided are tasting, touching, and experimenting the substances' reaction to different metals.
