As the pH of a substance rises from 7, it turns from a weak base to a strong base. A strong acid such as HCl, when mixed with water, will separate into molecules of hydrogen ions and chloride ions. That is called dissociation. Strong acids dissociate more completely than weak acids, ...
If the base dissociates completely to its conjugate acid and hydroxyl ions, then the base is strong. If the base dissociates partially, then the base is weak. The solutions of strong bases contain a higher concentration of hydroxyl ions OH- than the solutions of weak bases. What is the ...

Examples of Weak Passwords Hackers and computer intruders use automated software to submit hundreds of guesses per minute to user accounts and attempt to gain access. These tools use lists of dictionary words to guess the password sequentially. Some tools add common symbols, numbers, or signs that...
