The potassium has 1 electron on its outer shell.A chlorine atom has 7 electrons on its outer shell Potassium and Chlorine react to form Potassium Chloride The potassium and chloride ions will then have fu...
1st ionisation energy increases across a period as nucleus gets more positive, no further increase in shielding due to electrons being added to same shell, atomic radius decreases, attraction between nucl...
For example CH3COOH buffer Buffer is in equilibrium like this - CH3COOH = CH3COO- + H+When a little bit of Acid (H+) is added equilibrium shifts left (as equilibrium shifts in the opposite direction when ...
An increase in concentration increases the rate of reaction because there are more particles in the same volume. This m...
We know how to calculate pH from H+ concentration with the equation : pH = -log10[H+] So, we need to work out the concentration of H+ ions in 0.375 mol dm-3 of nitrous acid, HNOAnswered by • Chemistry tutor8701 Views
