gastric juices ph 1

1) Acidic - gastric juices pH 1, lemon juice pH 2.2, tomato juice pH 4.

2) Neutral - salt solution pH 7.

3) Alkaline - baking soda pH 9, bleach pH 13.

pH is a numeric scale used to specify the acidity or basicity of an aqueous solution.

When pH is less than seven (pH<7), solution is acidic.

When is equal seven (pH = 7), solution is neutral.  

When pH is greater than seven (pH > 7), solution is basic.

Sample Response: The nucleus of an atom has a positive charge because the proton is positive and the neutron is neutral.
