Answer is: A. test and determine the pH values of unknown solutions.
Acid-base indicators are usually weak acids or bases and they are chemical detectors for hydrogen or hydronium cations (pH or pOH values).
Example for acid-base indicator is phenolphthalein (molecular formula C₂₀H₁₄O₄). Phenolphthalein is colorless in acidic solutions and pink in basic solutions.
Another example is methyl orange. It is red colour in acidic solutions and yellow colour in basic solutions.

Answer:
Answer: 1.027 x 10^6 g= 1027kg
In this question, you are given the volume of the blimp (2.027×10^5 ft^3) and the density of the gas(0.179g/L). To answer this question, you need to convert the volume unit into liter. The calculation would be: 2.027×10^5 ft^3 x 28.3168L/ft3= 57.398 x 10^5L= 5.74x10^6L
Then to find the mass, multiply the volume with the density. The calculation would be: 5.74x10^6L x 0.179g/L= 1.027 x 10^6 g= 1027kg

Answer:
The answer to your question is below
Explanation:
A neutralization reaction is a chemical reaction between an acid and a base, and the products will be a binary or tertiary salt and water.
Examples
a) HCl + NaOH ⇒ NaCl + H₂O
b) H₂SO₄ + 2KOH ⇒ K₂SO₄ + 2H₂O
c) 2HNO₃ + Ca(OH)₂ ⇒ Ca(NO₃)₂ + 2H₂O
