Q: Know how to write the reactions for the ionization of acids and bases in water

ACIDS: H₃PO₄=H₃PO₄ + H₂O → H₂O⁺ + H₂PO₄⁻ HI=HI + H₂O → H₃O⁺ + I⁻ BASES: KOH=KOH → K⁺ + OH⁻ Sr(OH)₂=Sr(OH)₂ → Sr²⁺ + 2OH⁻ More test answers on https://studyhippo.com/chemistry-test-acids-and-bases/

Question 6

Know how to name acids and bases. also know how to write the formula from the name.

Answer

ACIDS W/ ONLY ONE ELEMENT: prefix hydro-, stem from element w/ the hydrogen, suffix -ic, word acid; HF- hydrofluoric acid ACIDS W/ 2+ ELEMENTS: contains hydrogen, oxygen, and another element/polyatomic ion; acids with polyacomic ions ending in -ATE, remove -ate and add -IC followed by word acid; acids w/ -ITE, drop -ite and add -OUS BASES: a metal and hydroxide (OH); called by ionic names (example: NaOH – sodium hydroxide

Question 7

What are the regulators of Acids and Bases equilibrium in the body

Answer

We control the amount of Buffers in our blood: 1. Respiratory system (Responses in minutes to hours) • Increased Respirations = Decreased CO2 • Decreased Respirations = Increased CO2 2. Renal system (Response in hours to days) The kidneys maintain homeostasis through excretion of waste products. •During Acidosis: • Reabsorbed HCO3 from tubular fluid • Secrete more H+ into collecting ducts to generate more bicarbonate; and more NH3 buffer is formed. •During Alkalosis: • Reabsorbed hydrogen ions •Secrete more HCO3 and NH3
