Is HLN an acid or base?
Is HLN an acid or base?
acidic indicator
Hln is an acidic indicator (KInd=10−7) which dissociates in aqueous acidic solution of 30 mL of 0.
Is bromide an acid?
It is one of the strongest mineral acids. When gaseous hydrogen bromide (highly toxic and extremely soluble in water) is dissolved in water, a highly acidic and corrosive liquid (HBr) is formed. It is commercially available as 48 or 62% acid in bottles.
How do you identify if its an acid or a base?
To determine whether a substance is an acid or a base, count the hydrogens on each substance before and after the reaction. If the number of hydrogens has decreased that substance is the acid (donates hydrogen ions). If the number of hydrogens has increased that substance is the base (accepts hydrogen ions).
Is HLN a weak acid?
Acid-base indicators are solutions of a weak acid (Hln), and its conjugate base (Ini} For particular indicator; the Hln form has a yellow colour; and In is red: HIn Hzo yeilow H;o: When acid is added to solution containing this indicator.
What are acid-base indicators 10?
Indicators: Indicators are those substances which tell us whether a substance is acidic or basic by change in colour….CBSE Class 10 Chemistry, CBSE- Acids, Bases and Salts.
| Indicator | Acids | Bases |
|---|---|---|
| 1. Red litmus | remains red | turns blue |
| 2. Blue litmus | turns red | remains blue |
| 3. Phenolphthalein | colourless | pink |

What is Bromite ion?
Bromite is a monovalent inorganic anion obtained by deprotonation of bromous acid. It is a bromine oxoanion and a monovalent inorganic anion. It is a conjugate base of a bromous acid.
Is bromide a base?
Solution : The chemical reaction involving bromide ion is gives as, `Br^(-) + H^(+) to HBr`. Bromide ion is a proton acceptor. Hence it acts as Lowry-Bronsted base.
How can you distinguish an acid from a base without an indicator?
Read on to find out how you can easily distinguish between acids and bases—no lab equipment necessary….Acids: Acids have the following characteristics:
- They’re sticky.
- They taste sour.
- They have a sickly sweet smell, like soured milk.
- They have a pH of less than 7.0.
- They produce hydrogen gas and salt in reaction to metal.
