David has bleach and water and mixes them together.
a. did david increase or decrease the ph of the water?
b. what type of ion was added to the water?

A) increase Ph B) incorporated ions: Na⁺ and ClO⁻

Explanation:

Bleach is the regular name for sodium hypochlorite (NaClO). This salt is basically composed by the cation sodium (Na⁺) and anion hypochlorite (ClO⁻), and when dissolved in water, this salt makes Ph goes above 7, this is, a basic Ph (will be increased)  - have in mind that, a Ph below 7 is acid, and a Ph above 7 is basic)

This will occur since, when ClO⁻ is dissolved in water:

ClO⁻ + H2O → HClO + OH⁻ according to this reaction, the hydroxyl anion will increase the Ph of the water

Finally, when dissolving bleach in water, you will be incorporating ions Na⁺ (sodium) and ClO⁻ (hypochlorite)

the answer is: they rebelled against saddam hussein’s rule.

kurds opposed saddam rule and wanted independence. kurds in the north and shiites in the south revolt against hussein.

for example, the halabja attack in 1988 conducted against the kurdish people by the iraqi regime under saddam hussein, where between 4000 people are killed and around 9000 are injured.
