Is these true or false:

-Every Bronsted-Lowry acid is also a Lewis acid.

-Conjugate acids of weak bases produce more acidic solutions than conjugate acids of strong bases.

Thank you very much!

Answer to #1 is here.

I think #2 is true.

thank you DrBob222!!!!!!!!!!!!!!!!!!!!!!!!!!!!have a great night!

thank you

also

why false for #1?

thanks a million

The reference I gave you explains exactly why it is false. Scroll down about half way on the page to Bronsted acidity....

To determine whether these statements are true or false, we need to understand the concepts of Bronsted-Lowry and Lewis acids, as well as the acidity of conjugate acids.

1. Every Bronsted-Lowry acid is also a Lewis acid:
A Bronsted-Lowry acid is a substance that donates a proton (H+) in a chemical reaction, while a Lewis acid is a substance that accepts an electron pair in a reaction. Since a Bronsted-Lowry acid that donates a proton can also accept an electron pair, it can act as a Lewis acid. Therefore, the statement "Every Bronsted-Lowry acid is also a Lewis acid" is true.

2. Conjugate acids of weak bases produce more acidic solutions than conjugate acids of strong bases:
To determine the acidity of a solution, we need to consider the strength of the conjugate acid of a base. A strong base has a relatively weak conjugate acid, while a weak base has a relatively strong conjugate acid. The acidity of a solution is determined by the concentration of H+ ions it contains. Since a strong base has a weak conjugate acid, it will produce fewer H+ ions when it dissociates, resulting in a less acidic solution. Conversely, a weak base with a strong conjugate acid will produce more H+ ions upon dissociation, leading to a more acidic solution. Therefore, the statement "Conjugate acids of weak bases produce more acidic solutions than conjugate acids of strong bases" is true.

In conclusion, both statements are true. Every Bronsted-Lowry acid is also a Lewis acid, and conjugate acids of weak bases produce more acidic solutions than conjugate acids of strong bases.
