Duestion 14 of 25 > In some chemical reactions, electrons are transferred from one substance to another, but there is no net gain or loss of electrons during the reaction. These reactions involve the oxidation, or loss of electrons, of one substance, and the reduction or gain of electrons, of another. This type of reaction is called a redox reaction. In neutral atoms, such as A and X, the number of protons equals the number of electrons. When atom A loses an electron, the positive charge of the nucleus becomes greater than the negative charge of the electrons, and the resulting ion has a net positive charge, forming a cation. In a reaction, the electron must be taken up by another atom, X, which results in more electrons than protons and a net negative charge on the atom, forming an anion. Mnemonic devices can help in remembering the definitions of oxidation and reduction. Two common mnemonic devices are • LEO (Losing Electrons: Oxidation) says GER (Gaining Electrons: Reduction), and •…
Which statements are true regarding redox reactions? (Note that in redox reactions, the molecule that “causes” another to gain or lose electrons is referred to as the agent.) Select all that apply. Oxidizing agents may accept H+ ions. If a molecule accepts electrons, it has been reduced. Oxidizing agents accept electrons. Reducing agents may accept H+ ions. Redox reactions may involve the transfer of hydrogen ions (H+). A molecule that has gained H atoms is said to be reduced.
c) Alum, KAl(SO4)2-12 H₂O is a soluble salt hydrate. Alum has several household and industrial uses. When placed in water alum dissociates into 3 ions and the water molecules become liquid water. Write the dissociation reaction of alum in water: Consider what you have learned about which ions under hydrolysis in water and which do not. Which ions hydrolyze in water? Write the hydrolysis reaction for each ion that hydrolyzes. Look over your Part II analysis and find the K, and/or Ks values for each of the ions that hydrolyze. Write the values next to their hydrolysis reactions above. Is alum is acidic, basic or neutral? How did you make your determination?

Strong acid-base reactions are a subcategory of double displacement reactions. The hydrogen ion of the acid "switches places" with the cation of the base, while the hydroxide ion of the base "switches places" with the anion of the acid. 1.

Write the correct product(s) of the following reaction. Include physical states! Also balance the chemical reaction by writing correct coefficients. _NaOH(aq) + H SO (aq) 3. Suppose it takes 10 mL of 0.1 M HCl to neutralize 10 mL of 0.1 M NAOH. (“M" = molarity, which is a unit of concentration.) How many milliliters of 0.1 M H,SO, do you expect will be needed to neutralize 10 mL of 0.1 M NaOH? Explain your choice.
