Determining the pH of an acid and base in various situations by working with concentrations. A multi-step question.

Part 1: What is the pH of a solution of 1M HCO3 and 1M CO3? Part 2: What is the pH if it was mixed with an equal volume of water? Part 3: What is the pH if it was mixed with an equal volume of 0.001 M HCl? Part 4: What is the pH if it was mixed with an equal volume of 0.001 M NaOH?

Chemistry

Explain the following terms: Addition reaction Homolysis and heterolysis Nucleophile and electrophile Hence a) explain briefly why alkanes react only by homolysis b) show the mechanism of the nucleophilic substitution of bromoethane with sodium hydroxide Q3. There are four compounds, A-D, all with molecular formula C4H8. Compound A is a cis-isomer and compound B is a trans-isomer. Both react with concentrated sulphuric acid, followed by water to yield a compound E of formula C4H10O. Compound C reacts with sulphuric acid followed by water, to yield mostly compound E, but also some compound F, also C4H10O. Compound D also reacts reacts with sulp... click for more
