Debt collectors can contact you by phone, letter, email or text message to collect a debt, as long as they follow the rules and disclose that they are debt collectors.
Acidic and basic are two extremes that describe a chemical property chemicals. Mixing acids and bases can cancel out or neutralize their extreme effects. A substance that is neither acidic nor basic is neutral. The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6. The same holds true for pH values above 7, each of which is ten times more alkaline (another way to say basic) than the next lower whole value.
An acid with pH 1 is said to be very strong, and as the pH value increases, acidity is decreased. The pH values more than 7 indicate basicity. As the basicity increases, pH value will also increase and strong bases will have pH value 14. pH papers are indicators which are easy to use.
