<h3>Answer:</h3>

The higher the hydronium ion concentration of a solution, the <u>lower</u> its pH.

<h3>Explanation:</h3>
  • The pH is the measure of acidity or alkalinity of a substance.
  • We calculate pH by using;

                  pH = -log[H+]

  • The lower the pH of a solution the more acidic it is and the higher the pH the more basic or alkaline it is.
  • pH =-log[H+] =-log[H₃O+]
  • From this relationship, the higher the hydronium ions concentration of a solution the lower the pH and the more acidic a solution is.

For example,

Solution A with a [H₃O+] of 0.003 M will have a pH of

pH = -log 0.003 M

     = 2.52

While, a solution B with a [H₃O+] of 0.025 M will have a pH of

pH = -log 0.25 M

    = 1.60

Therefore, the higher the concentration of hydronium ion of a solution the lower its pH is.

Hamid made this table to organize his notes on the properties of acids and bases.
Molodets [167]

Answer : The property in the wrong column is, base form hydrogen gas with metals

Explanation :

Acid : It is a substance that has ability of donating a proton or hydrogen ion, H^+.

The properties of an acid are :

  • Acids are sour in taste.
  • It conduct electricity.
  • The texture of an acid solution is sticky.
  • It react with carbonates to give salt.
  • It changes the color of the litmus paper to red.
  • It react with a metal to give compound and hydrogen gas.

Base : It is a substance that has ability of donating hydroxide ion, OH^-.

The properties of an base are :

  • Base are bitter in taste.
  • It conduct electricity.
  • The texture of an base solution is slippery.
  • It changes the color of the litmus paper to blue.
  • It does not react with a metal.

Hence, from the above information, we conclude that the property in the wrong column is, base form hydrogen gas with metals .

What are the chemical properties of acids​
Oliga [24]

Answer:

Acids are sour in taste. Acids react with carbonates and hydrogen carbonates to form a salt, water, and carbon dioxide gas. Extremely active metals such as Potassium (K), Calcium (Ca), Sodium (Na), etc tend to explode when combined with acids. Weak Acids like Carbonic Acid doesn't act with any metal at all.
