Re: How to tell?
bronsted acid usually has an H in it, like HCl, H2SO4, since it can donate H+
bronsted base usually has an OH in it, like NaOH and KOH, so it can accept the H+ from acid to form H2O.

Re: How to tell?
Typically acids have a hydrogen atom. For instance HCl and HPO+
Also acids can typically gain a hydrogen atom for solutions involving water for instance NH3 + H2O (double arrows in both directions) NH4^+ OH^-
H2O is the acid and NH4^+ is the conjugate acid

Re: How to tell?
Acids usually contain hydrogen since acids are defined as substances that donate hydrogen ions.

Re: How to tell?
Acids typically donate a proton. For example, with HCl aqueous it beomes H+ and Cl-.

Re: How to tell?
Acids typically have a hydrogen since it donates protons (ex: HCl). Bases will have hydroxide (OH) in their formula for you to identify (ex: sodium hydroxide: NaOH).

Re: How to tell?
Given a chemical equation, you can determine which substance is the acid by counting the hydrogens on each substance before and after the reaction. If the number of hydrogens has decreased, that substance is an acid since acids are hydrogen ion donors.

Is there any way to confirm if it is an acid or base without a chemical equation?

Re: How to tell?
Sometimes it can be difficult to tell whether a given molecule is an acid or a base from its molecular formula alone. For example, NH3 (ammonia) is a weak base despite having several H atoms.
