H2O
What is the pH of a solution with [H+] = 10-11
pH = 11
This is a base.
pH is close to 14
What is strong base?
Which pHs of acids are dangerous?
pH 0-2
Produces hydroxide ions (OH-) in solution
What is a base?
Which of the following is NOT a strong acid?
HCl, HF, H2SO4
HF
When an acid and a base combine to form water and salt.
What is neutralization?
What are electrolytes?
What is anything that dissociates into separate ions
The generic chemical equation for a neutralization reaction.
What is acid + base -> water + salt?
Has pH range of 8-14
What is a base?
What is a proton donor?
What is an acid?
When water dissociates, it splits into
H+ and OH- ions
HCl complete dissociates in water. Hydrochloric acid is a ____________ acid.
What is a strong acid?
Neutral water has equal amounts of ____ and ____
H+ and OH- ions
Produces hydronium ion (H3O+) ions in solution
What is an acid?
What is a proton acceptor?
What is a base?
Is all water completely neutral? Explain why
No, because some water has more H+ in solution and some has more OH - in solution. For example, waters in streams are slightly basic. Water in rain is slightly acidic.
Baking soda has a pH close to 7 and has a few OH- ion. Baking soda is a _________________.
What is weak base?
When an acid reacts with a metal, what does it produce?
Hydrogen gas (H2) and salt (for ex: MgCl2)
Water when it is with KOH in solution
What is an acid?
If you increase [H+], what happens to acid strength AND pH?
If you increase H3O+, the acid strength will increase and the pH value will go down.
When chemicals split into their substituent ions
What is dissocation?
NaOH is a strong base. That means that it ________ dissociates into ________ and ________ ions
Completely
Na+ and OH-
How many times stronger is a base with a pH of 10 vs. a pH of 8?
100x
