Generally there are two kinds of bleaching agents, notably chlorine (and many chlorine compounds such as sodium hypochlorite) and peroxygen bleaching agents (such as hydrogen peroxide). This isn't to say there aren't others, because there are, such as ammonia. (Note, mixing traditional bleaches and ammonia is very dangerous)

Why does the pink color, which forms at the point where NaOH comes into contact with the solution (HCl) in the flask, disappear
Novay_Z [31]
Answer is: because pH value of solution is changing.
Balanced chemical reaction: NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l).
pH of sodium hydroxide solution is above seven (basic), when solution of hydrochloric acid is added, pH slowly dropping until it became neutral solution (pH is equal seven) and that is endpoint of titration.

Lithium metal reacts with nitrogen gas to form lithium nitride. identify the balanced reaction that describes this process
Arlecino [84]

Lithium metal reacts with nitrogen gas to form lithium nitride the balanced chemical equation will be 6Li + N₂ → 2Li₃N.

<h3>What is a balanced chemical reaction?</h3>

In a balanced chemical reaction, the number of moles that are present at the side of the reactant must be always equal to the side of product formation this is known as a balanced chemical equation.

The balanced chemical reaction will be 6Li + N₂ → 2Li₃N.

Here 6 moles of lithium is reacting with one nitrogen but as it is in gaseous state it is N₂ after reacting with lithium it will give two moles

Therefore, balanced equation will be 6Li + N₂ → 2Li₃N

What are the ions in these compounds?<br> a. NH4BY b. K2HPO4 c. CUNO3
Ann [662]

Explanation:

If the compounds are dissociated, the ions are:

         NH₄BY             NH₄⁺   BY⁻

        K₂HPO₄             K⁺      HPO₄²⁻

        CuNO₃              Cu⁺     NO₃⁻

The given compounds assuming that they dissociate in solutions  will produce the ions listed above.

The cations which are the positively charged ions in the above compounds are made up of metals and radicals.

The anions which are negatively charged ions are purely chemical radicals.
