pH of water `…………` with increase in temperature.

STATEMENT-1: pH of water decreases with increase in temperature. STATEMENT-2 : K_(w) of water decreases with increase in temperature.

Assertion (A): pH of water increases with an increase in temperature. Reason (R) : K_(w) or water increases with increase in temperature.

Assertion: The value of ionic product of water (K_w) increases on increasing the temperature. Reason: The ionisation of water increases with an increase in temperature.

DO (dissolved O_(2) ) of water _________ with an increase in temperature.

The solubility of most substances in water increases with increase in temperature. True or false?

STATEMENT-1: Autoprotolysis constant of water increases with the increase in temperature. STATEMENT-2: When a solution of a weak monobasic acid is titrated wita a strong base, at half neutralization point pH=pK_(a)+1. STATEMENT-3: The pH of 10^(-8) m HCl is 8.

The solubility of NaCl in water decreases with increases in temperature.

Assertion: pH of water increases on increasing temperature. Reason: H_(2)O rarr H^(+) + OH^(-) is an exothermic process.

With increases in temperature pH of pure water

Assertion (A): Ionic conductivities increase with increase of temperature and pressure. Reason (R): Viscosity of water decreases with increasew of temperature and increases with the increases of pressure.
