Identify acids and bases based on their pH. Understand and balance a Neutralization reaction. pH Neutral Neutralization Key Words
When dissolved in water, A/B dissociate to ions. HNO 3 (s) (aq) + NO 3 - (aq) H+H+ Hydrogen ion is responsible for acid properties. Ca(OH) 2 (s) Ca +2 (aq) + 2 (aq) OH - Hydroxide ion is responsible for base properties.
The strength of an acid or a base is measured using the pH scale. acidic pH 0 - 6.9 low numbers mean strong acid, higher numbers mean weak acid. basic pH 7.1 - 14 low numbers means weak base, higher numbers means strong base. pH 7: neutral - not acidic, not basic.
Neutralization reaction: Mixing acid and base - they destroy each other to form a salt (ionic bond) and water. Cl + Na NaCl + H 2 O Acid + base salt + water Neutralization is A double replacement reactions. HOH
Acids and bases destroy each other – neutralization Neutralization is a double replacement reaction. Products of neutralization: Water – H + of the acid plus OH - of the base. + + Acid base HOHK H2OH2O BrHOHKBr Salt - positive ion (metal) of the base and the negative ion of the acid. saltwater
