Between 1968 and 1972, Spitz won nine Olympic golds plus a silver and a bronze, five Pan American golds, 31 Amateur Athletic Union (AAU) titles, and eight National Collegiate Athletic Association (NCAA) titles.During those years, he set 35 world records, but two were in trials and unofficial.efore he was 10, Spitz held 17 national age-group records, and one world record. At 14 his family moved to Santa Clara so Spitz could train with coach George F. Haines of the Santa Clara Swim Club. From 1964 to 1968 Mark trained with Haines at SCHS and Santa Clara High School.
The Arrhenius definition of an. acid is a substance that when dissolved in water increases the concentration of hydrogen ion, H+(aq). A base is a substance that when added to water increases the concentration of hydroxide ion, OH-(aq).
A hydrogen and a hydroxide ion can also join together to form a water molecule. In pure water, hydrogen and hydroxide ions are present in a 1:1 ratio since the only source of these ions is the ionization of water. Acids and bases are substances which change the balance of hydrogen and hydroxide ions in water. In this lesson, we will first explore the chemistry of acids and bases, then we will show how to calculate their concentration mathematically.
