A reducing agent is one which is oxidised in the reaction itself. When you take into account the oxidation numbers you will see that the Cl- ions are oxidised from an oxidation number of -1 to 0 in Cl2. Therefore Cl- ions are the reducing agent.

Determine the mass of KNO3 that dissolves in 100 grams of water at 40°C to produce a saturated solution

velikii [3]

From a solubility curve the solubility of KNO3 at 40°C is about 63 g / 100 g of water.

That means that 100 g of water at 40°C can dissolve 63 g of KNO3.

A saturated solution is one that cannot dissolve more solute, because it already has reached the greatest concentration that it can hold.

Then, the mass of KNO3 that dissolves in 100 g of water is about 63 g.

The melting point of the metal potassium is 63.5c, while that of titanium is 1660c. what explanation can be given for this great

kiruha [24]

The melting point of potassium = $63.5^{0}C$

Melting point of titanium = $1660^{0}C$

Titanium has a stronger metallic bonding compared to potassium. Titanium being a transition metal has greater number of valence electrons (4 valence electrons) contributing to the valence electron sea compared to potassium which has only one valence electron. The atomic size of Titanium much lower than that of potassium, so the bonding between Titanium atoms is stronger than that of potassium. Hence, the melting point of Titanium is much higher than that of potassium.
