PROBLEM: John Wayne Airport (IATA: SNA, ICAO: KSNA, FAA LID: SNA) is an international airport in Orange County, California, United States, with its mailing address in the city of Santa Ana, hence the IATA airport code. The entrance to the airport is off MacArthur Blvd in Irvine, the city that borders the airport on the north and east. Newport Beach and Costa Mesa form the southern and western boundaries along with a small unincorporated area along the Corona del Mar (73) Freeway. Santa Ana is just north, not actually touching the airport. Originally named Orange County Airport, the county Board of Supervisors renamed it in 1979 to honor actor John Wayne, who lived in neighboring Newport Beach and died that year.

SOLUTION: is santa ana the same as john wayne airport?

PROBLEM: In chemistry, pH (/piːˈeɪtʃ/) is a logarithmic scale used to specify the acidity or basicity of an aqueous solution. It is approximately the negative of the base 10 logarithm of the molar concentration, measured in units of moles per liter, of hydrogen ions. More precisely it is the negative of the base 10 logarithm of the activity of the hydrogen ion. Solutions with a pH less than 7 are acidic and solutions with a pH greater than 7 are basic. Pure water is neutral, at pH 7 (25 °C), being neither an acid nor a base. Contrary to popular belief, the pH value can be less than 0 or greater than 14 for very strong acids and bases respectively.

SOLUTION:
is it possible for ph to be negative?
