It is not just lab chemicals but also common household substances that can be classified as acidic, basic, and neutral materials

. This categorization is based on the concentration of hydrogen ion (H+), or hydronium ion (H3O+), and hydroxide ion (OH-) present in the solutions. Based on these ion concentrations, the pH or pOH can be calculated giving a quantitative assessment. Additionally, litmus paper or pH paper can be used to qualitatively determine if the solution is acidic, basic, or neutral. Red litmus paper turns blue in acid. Blue litmus paper turns red in base. pH paper gives a more precise pH number based on the color the pH paper turns when a small amount of solution is placed on the paper.
Most materials are either acidic or basic. Baking soda, bleach, codeine, detergent, egg whites, household cleaners, and seawater are basic because they have a high concentration of hydroxide ions in solution and pH above 7. Acid rain, beer, coffee, lemon juice, maple syrup, mouth wash, pickles, rain, soda, tea, tomatoes, and vinegar are acidic because they have a high concentration of hydrogen ions in solution and pH below 7. A few solutions have neutral pH due an equal concentration of hydrogen ions and hydroxide ions. Water is the only truly neutral substance but human blood, milk, plant food, saliva, and tofu are very close to neutral pH with nearly equal hydrogen ion and hydroxide ion concentration and pH near 7.

Listed in the Item Bank are key terms and expressions, each of which is associated with one of the columns. Some terms may display additional information when you click on them. Drag and drop each item into the correct column. Order does not matter.

Acidic: coffee, orange juice , soft drink, vinegar

Basic: Antacid, Baking soda, Detergent, Lye, Milk of Magnesia

Neutral: water, Sugar, Table salt.

<u>Explanation:</u>

Acidic substances have high concentration of hydrogen ions and have pH value less than 7. Basic substances have high concentration of hydroxide ions and have pH value more than 7. Neutral substance have pH value 7. The concentration oh hydrogen ions and hydroxide ions is equal.

Salt is formed when a acid reacts with base in a neutralization reaction. Different types of salt are formed depending upon the concentration of hydrogen and hydroxide ions. Neutral salt is formed when concentration of hydrogen ion is equal to concentration of hydroxide ions.

Coffee, orange juice , soft drink, vinegar are acidic substances. Antacid, Baking soda, Detergent, Lye, Milk of Magnesia. water, Sugar, Table salt are neutral substances.

How are electromagnetic waves able to travel without a medium?
vazorg [7]
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. this means that electromagnetic waves can travel not only trough air and solid materials, but also trough the vacuum of space.

Imagine two billiard balls on a pool table. Ball A has a mass of 2 kilograms and ball B has a mass of 3 kilograms. The initial v
ratelena [41]
1. The balls move to the opposite direction but the same speed. This represents Newton's third law of motion.
2. The total momentum before and after the collision stays constant or is conserved.
3. If the masses were the same, the velocities of both balls after the collision would exchange.
4 and 5. Use momentum balance to solve for the final velocities.
