pH+Practice

Name; Date: 8th Grade Science – STEM Middle Academy Block: pH Practice Identify the following chemicals as either acids or bases. Why is water sometimes written as HOH instead of H2O? Determine the pH of the following. A student wants to know whether a chemical compound’s pH will change if an acid or a base is added to it. Describe a procedure they could follow to figure this out.
 * 1) H2SO4:
 * 2) NaOH:
 * 3) HCl:
 * 4) KOH:
 * 5) HCH3:
 * 1) A chemical compound 10 times more acidic than pure water.
 * 2) A chemical compound that turns litmus paper red and is 10 times stronger than the chemical in question 1 above.
 * 3) The strongest base.
 * 4) Distilled water.
 * 5) An acid 10,000 times stronger than water.
 * 6) A base that is 1 million times stronger than HCl (ph = 2.0)
