False
Not all compounds that contain hydrogen are classified as acids. Acids are defined as substances that can donate protons (H+ ions) in a solution. While many acids do contain hydrogen, there are also numerous compounds with hydrogen that do not exhibit acidic properties. For instance, water (H2O) contains hydrogen but is not an acid. Similarly, hydrocarbons (like methane, CH4) consist of hydrogen and carbon yet do not behave as acids. Therefore, the claim that all hydrogen-containing compounds are acids is incorrect.
