Question

name _ date _ period _ ph exit ticket directions: read each question carefully and place an \x\ next to the correct answer. 1. what does the ph scale primarily measure? the temperature of a solution the mass of dissolved salt in a solution the acidity or basicity (alkalinity) of a solution the volume of a container 2. which ph value is characteristic of a strong base (alkali)? ph 7 ph 6 ph 2 ph 13 3. which of the following describes a solution with a ph of 7? weak acid strong base strong acid neutral 4. when an acid and a base are mixed together in a neutralization reaction, what are the two main products formed? salt & water oxygen gas & acid sugar & water hydrogen gas & base 5. an acid is consideredstronger than another acid. on the ph scale, how will the ph of the stronger acid compare? it will be closer to ph 0 it will be closer to ph 14 it will be exactly ph 7 it will be closer to ph 7

Explanation:

1. The pH scale is a measure of how acidic or basic a substance is.
2. A strong base has a high pH value. pH 13 is a high value.
3. A pH of 7 is neutral.
4. In a neutralization reaction, an acid and a base react to form salt and water.
5. A stronger acid has a lower pH value, so it is closer to pH 0.

Answer:

1. The acidity or basicity (alkalinity) of a solution
2. pH 13
3. Neutral
4. Salt & Water
5. It will be closer to pH 0
